Hitachi Elevator Power Board HAA2006C – The 24 V Power-Heart That Keeps Every Hitachi Lift Alive

Behind every silky ride and every illuminated button is a green A5-sized PCB that never sleeps — the HAA2006C power board. Designed by Hitachi for NPX, NEX and GVF-L systems, this 24 VDC, 6 A switch-mode supply feeds logic, encoders, brakes and hall lanterns while providing short-circuit, over-temperature and brown-out protection. Nanjing Zhuye Elevator Parts keeps factory-sealed HAA2006C units in anti-static stock for next-day despatch. Below we explain what the board does, how to install it in under ten minutes, and the replacement cycle that prevents expensive “no power” call-backs.
1. What HAA2006C Really Is
-
Input: 220 VAC ±10 %, 50/60 Hz, 1.2 A max
-
Output: 24 VDC ±1 %, 6 A continuous, 10 A peak <5 s
-
Protection: OCP, OVP, OTP, brown-out lock-out, auto-restart
-
Efficiency: 88 % — runs cool, saves energy
-
Ripple: <50 mV at full load — encoder-safe
-
MTBF: >100,000 h at 40 °C — 11 years continuous
-
Size: 160 × 100 × 45 mm — DIN-rail or chassis mount
-
Connectors: plug-in 6-way 250 series — swap without tools
If the board fails, the car goes dark, the brake drops, and the CPU logs “24 V Fault”.
2. Where It Is Used
-
Hitachi NPX, NEX, GVF-L passenger elevators 1.0–2.5 m s⁻¹
-
Chinese MRL controllers with 220 VAC input and 24 VDC bus
-
Modernisation kits upgrading relay logic to VVVF
-
Suitable for machine-room or machine-room-less installations
3. Installation – 10-Minute Hot Swap
Safety: place lift on inspection, lock main breaker, tag out, wait 60 s for DC bus to discharge.
-
Photograph wiring — note colour codes.
-
Remove old board — undo 2 DIN-rail clips; unplug 6-way input and 4-way output.
-
Inspect terminals — if burnt, replace plug (Nanjing Zhuye part HP-6P).
-
Snap HAA2006C onto rail until latches click; earth strap to PE.
-
Connect plugs:
-
J1: L/N/Earth (220 VAC)
-
J2: +24 V/0 V/Earth (output)
-
-
Power on — green LED steady, output 24.0 ±0.2 V measured at J2.
-
Run one full trip — verify brake pick, encoder and hall lanterns all active.
No laptop is required; voltage is preset at the factory.
4. Daily Operation – What the Board Actually Does
-
Supplies 24 V to: brake coil, encoder, COP, LOP, gong, overload cell
-
Auto-restarts after 3 s delay if mains dip <200 V — no nuisance shutdowns
-
Temperature sensor derates output above 70 °C — no summer blackouts
-
Built-in self-test every 24 h — if output <22.8 V, “24 V Fault” is logged
-
Ripple <50 mV — encoder count stable, no ghost trips
5. Replacement Cycle & Preventive Maintenance
-
High-traffic office (>1,000 starts day⁻¹) – blow dust every 3 months, replace board every 6 years
-
Residential tower (300–600 starts day⁻¹) – inspect annually, replace every 10 years
-
Low-rise freight (≤200 starts day⁻¹) – inspect every 18 months, replace every 12 years
Replace immediately if:
-
Output ripple >100 mV (oscilloscope test)
-
Temperature >85 °C with normal ambient
-
Brown-out restart >3 times in 30 days
-
LED flicker or no green light after 3 s
-
EEPROM error 0xE2 after power dip (parameter corrupt)
6. Extending Life – 3 Pro Tips
-
Keep ambient <40 °C; every 10 °C rise halves capacitor life
-
Torque lugs annually; loose connections cause arcing and ozone
-
Close cabinet door; dust on heat-sink is the #1 killer
7. Why Buy HAA2006C from Nanjing Zhuye Elevator Parts?
-
Factory-new, not refurbished; passes 4-hour burn-in at 60 °C full load
-
Output voltage preset; matches Hitachi original tolerance, no re-adjustment
-
Anti-static foam box + silica gel — safe for air freight
-
Dual stock: 520 pcs Nanjing, 180 pcs Dubai — next-day delivery to 65 countries
-
Bundle kit: board + 6-way plug + 2 m output cable — 5 % discount
-
24 months warranty against drift or over-temperature failure
-
7×24 WhatsApp/WeChat video support; average response 10 minutes
Conclusion
The HAA2006C power board is the unseen heart that pumps 24 V life into every Hitachi lift. A single voltage dip can park a car for hours. Keep a spare from Nanjing Zhuye on every service truck, swap it on schedule, and replace “no power” panic with a ten-minute planned fix — one calm, energized ride at a time.
