- 구조 & Common Fault Points of Integrated Power Supply Board
Mounting Position of Power Board
After removing the rear cover of the unit, the independent power supply area on the left side of the mainboard is the dedicated PP400 power supply board.
Integrated components: EMI filter, DC-DC step-down IC, backlight inverter circuit, 퓨즈, energy storage backup capacitors, 950mAh mainboard backup lithium battery (3-year service life).
Typical Power Board Fault Matrix
| 결함 증상 | Root Cause on Power Board | Maintenance Solution |
| No indicator light when powered on, black screen fails to boot | 1. Blown input fuse | Replace fuse, electrolytic capacitors and power management IC; test for short circuits on downstream circuits |
| 2. Bulging & leaking 24V filter capacitor | ||
| 3. Burnt main DC-DC chip | ||
| Screen flashes briefly then goes black, no backlight | Damaged backlight inverter boost coil / MOSFET | Replace components in backlight driver circuit |
| Boots normally but restarts frequently with voltage fluctuation | Degraded backup capacitors, cold solder joints on input terminals | Resolder terminals, replace buffer energy storage capacitors |
| System time lost, all parameters cleared after power off | Depleted mainboard backup lithium battery | Replace original Renata 950mAh battery |
| Unstable touch response, intermittent communication disconnection | Excessive ripple voltage from power board, failed filtering circuit | Replace all electrolytic capacitors on low-voltage output channels |
- 호환 가능 & Replacement Models within the Same Series
4.1 Direct Drop-in Original Models with Identical Hardware Base (Fully interchangeable program & 장착 치수)
4PP420.0571-K05 (basic low-end version, identical memory specification)
4PP420.0571-75 (standard original sales model without K wide-temperature suffix)
4.2 Standalone Power Board Spare Part Compatibility
Power supply boards for all 5.7-inch PP400 units are interchangeable: all 4PP420 models with 0571 hardware base share identical power boards.
Incompatible models: 4PP045 (4.3-인치), 4PP650 (6.5-인치) – differing power board dimensions and output circuits prevent cross-use.
4.3 Upgraded Replacement Units (Discontinued Product Generation Upgrade)
새로운 모델: 4PP320.0571-K15 / 5PP420.0571 (Power Panel 300/500 시리즈; LED backlight replaces legacy CCFL, optimized power board architecture)
- Supporting Software & 프로그래밍 환경
- 프로그래밍 소프트웨어: Automation Studio V4.0~V4.9 (higher versions incompatible with legacy PP400 hardware)
- Runtime System: Automation Runtime industrial real-time operating system
- 통신 인터페이스: Ethernet TCP/IP and RS232 support connection to B&R X20/X60 controllers and third-party PLCs
- Firmware Repair Note: Abnormal power supply from the power board may corrupt CF card system files; re-flash firmware to restore project programs after power board maintenance.
- 일반적인 애플리케이션 시나리오
Plastic injection molding machines, 섬유 기계, packaging production lines, woodworking equipment, small production line control cabinets.
Suitable for compact installation space, 24VDC power supply and panel embedded mounting environments.
- 획득 & Maintenance Instructions
- New Units: Discontinued by original manufacturer; only second-hand refurbished / dismantled complete units and standalone power board spare parts available on market.
- Key Maintenance Points: After power board replacement, full voltage testing of 3.3V/5V/12V outputs is mandatory; complete touch screen calibration and back up CF card project programs.
