Elevator MAC Car Lighting Controller Power Supply POWCV24181MH – Nanjing Zhuye Elevatorparts
The elevator car lighting system is a key part of ensuring passenger comfort and safety during rides, and the power supply serves as the “energy core” for the stable operation of the MAC car lighting controller. The Elevator MAC Car Lighting Controller Power Supply POWCV24181MH provided by Nanjing Zhuye Elevatorparts is a high-performance power supply component tailored for MAC elevator car lighting controllers. It is perfectly compatible with MAC series lighting control systems and widely applicable to various types of passenger and freight elevators. This power supply converts the elevator’s input voltage into a stable 24V DC power supply, providing reliable energy support for the car lighting controller, ensuring consistent brightness of car lights and stable operation of dimming functions. Crafted with high-quality electronic components, a precision voltage regulation module, and a heat-dissipating shell, it meets international electrical safety standards (IEC 61347, GB/T 19510) and has become a trusted choice for global elevator maintenance teams and manufacturers.
Nanjing Zhuye Elevatorparts adheres to the core philosophy of “Stable Power Supply, Safe Operation” and implements strict quality control throughout the production process of the POWCV24181MH power supply. Each unit undergoes rigorous testing, including voltage stability calibration, load-bearing capacity verification, ripple coefficient detection, and temperature rise testing, ensuring stable parameters (output voltage 24V DC, output current 18A, ripple ≤ 50mVp-p) and long-term reliable operation. The power supply adopts a high-efficiency switching power supply design with conversion efficiency ≥ 88%, effectively reducing energy consumption. Its aluminum alloy heat-dissipating shell enhances heat dissipation performance, allowing it to operate stably in the temperature range of -20℃ to 60℃. The built-in overvoltage, overcurrent, short-circuit, and overtemperature protection functions can quickly cut off the power supply in abnormal situations, effectively protecting the MAC lighting controller and car lighting components from damage. The waterproof and dustproof design (IP44 protection rating) also makes it suitable for the slightly humid and dusty environment of the elevator car top or control cabinet.
Usage Guide for Elevator MAC Car Lighting Controller Power Supply POWCV24181MH
Correct installation, wiring, and use are crucial to maximizing the performance and service life of the POWCV24181MH power supply. Nanjing Zhuye Elevatorparts recommends that only certified elevator electrical technicians perform installation and maintenance to avoid electrical faults or safety hazards caused by misoperation.
1. Pre-Installation Preparation
1. Pre-Installation Preparation
First, confirm that the elevator’s MAC car lighting controller model matches the POWCV24181MH power supply (check parameters such as input voltage, output voltage, output current, and installation dimensions). Consult Nanjing Zhuye Elevatorparts’ technical team if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and the secondary power supply for the car lighting system, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator landing doors and machine room entrance. Locate the power supply installation position (usually on the car top or in the car control cabinet) and clean the area to remove dust, debris, and oil stains. Finally, prepare professional tools such as a screwdriver, wire stripper, multimeter, and insulation tester, and check that the new POWCV24181MH power supply from Nanjing Zhuye Elevatorparts is intact (no damage to the shell, no loose pins).
First, confirm that the elevator model and electrical system parameters match the KKB4-3F-20 emergency stop switch (check parameters such as rated voltage, rated current, and installation dimensions). Consult Nanjing Zhuye Elevatorparts’ technical team if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and secondary power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator landing doors and machine room entrance. Enter the elevator pit after ensuring the elevator car is stabilized with mechanical supports to prevent accidental movement. Finally, prepare professional tools such as a screwdriver, wire stripper, multimeter, and insulation tester, and clean the switch installation position in the pit to remove dust, debris, and water stains.
2. Installation & Wiring
2. Installation & Wiring
If replacing the old power supply, first take photos to record the wiring positions of the old power supply (input and output terminals) for later reference. Disconnect the wiring of the old power supply according to the recorded labels and remove the old power supply. Take the new POWCV24181MH power supply, fix it on the installation bracket with screws, and ensure it is installed firmly and horizontally (facilitating heat dissipation). Connect the wires strictly following the wiring diagram provided by Nanjing Zhuye Elevatorparts: connect the elevator’s input power cable to the “INPUT” terminal of the power supply, and connect the output cable to the MAC lighting controller’s power input terminal (note the positive and negative poles, and do not reverse them). After wiring, use a screwdriver to tighten the terminal screws to avoid poor contact. Use a multimeter to check the continuity of the wiring and ensure no short circuit exists between the positive and negative poles.
Debugg3. Operation & Daily Maintenance
Restore the power supply of the car lighting system and switch the elevator to inspection mode. Observe the operation of the car lights: they should turn on normally, with stable brightness and no flickering. Use a multimeter to measure the output voltage of the POWCV24181MH power supply, which should be stable at 24V DC (allowing a small deviation within ±0.5V). Test the dimming function of the lighting controller (if equipped) to ensure it operates normally. For daily maintenance, inspect the power supply during weekly car top patrols: check if the shell is damaged, deformed, or overheated; confirm the wiring terminals are tight, free of oxidation, or loose; clean the surface of the power supply with a dry cloth to remove dust (ensuring unobstructed heat dissipation). Every 3 months, use a multimeter to recheck the output voltage stability; every 6 months, inspect the power supply’s protection functions (e.g., short-circuit protection test can be performed under professional guidance). For elevators in high-humidity or high-temperature environments, shorten the maintenance interval to 1 month.
Replacement Cycle of Elevator MAC Car Lighting Controller Power Supply POWCV24181MH
The replacement cycle of the POWCV24181MH power supply is closely related to operating conditions and environment. Under normal circumstances (elevator daily operation 12-24 hours, car top temperature -20℃ to 60℃, stable input voltage, no frequent power fluctuations), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 3-4 years. This cycle is determined based on long-term field operation data, component aging tests, and global user feedback, fully considering the aging of internal electronic components, the attenuation of voltage regulation performance, and the wear of terminals.
For elevators in harsh environments (e.g., car top with frequent high temperature exceeding 60℃, high humidity, or heavy dust; coastal areas with high salt spray) or elevators with frequent power fluctuations (e.g., old buildings with unstable power supply), the replacement cycle should be shortened to 1.5-2.5 years. Harsh environments accelerate the corrosion of the shell and terminals, while frequent power fluctuations increase the load on internal components, accelerating aging. For low-usage elevators (e.g., villa elevators, small office buildings with daily operation time < 8 hours) in stable environments, the cycle can be extended to 4-5 years, but only after inspection and confirmation by Nanjing Zhuye’s technicians that the power supply’s output voltage stability, ripple coefficient, and protection functions meet factory standards.
Replace the power supply immediately if any of the following issues occur, regardless of its service life: The car lights flicker, dim, or fail to turn on, and the fault is confirmed to be caused by the power supply; the output voltage deviation exceeds ±1V (uncorrectable by debugging); the power supply shell is severely damaged, corroded, or has obvious overheating marks (discoloration, burning smell); the power supply triggers protection functions frequently (e.g., frequent shutdown due to overcurrent/overtemperature) without obvious external faults; multimeter testing shows the ripple coefficient exceeds 100mVp-p, affecting the normal operation of the lighting controller.
