Function Features

1. Four independent isolated regulated DC output rails to power mixed low-voltage logic, analog instrumentation and communication hardware simultaneously
2. Active power factor correction minimizes mains harmonic distortion and reduces facility power consumption
3. Automatic short-circuit recovery: power supply restarts automatically after short-circuit fault removal without manual power cycle
4. Built-in thermal temperature sensor triggers gradual power derating before full thermal shutdown protection activation
5. Front panel LED indicator for AC mains input status, global power good signal, over-temperature fault alarm
6. Parallel operation support for load current redundancy expansion via dedicated current-sharing bus interface
7. Remote on/off control signal input for centralized cabinet power sequencing and emergency shutdown logic integration

Material Composition

• Outer Enclosure: Cold-rolled steel fully enclosed chassis with powder-coated anti-corrosion surface treatment
• Internal Power Circuit Substrate: High-temperature FR4 heavy copper PCB for high-current power trace conduction
• Power Conversion Core Components: High-efficiency resonant switching transformers, low ESR bulk electrolytic capacitors, silicon carbide switching MOSFETs, isolated feedback optocouplers
• Terminal Connectors: Nickel-plated copper high-current screw terminals for AC input and DC output wiring

Structural Characteristics

• Fully enclosed metal chassis with integrated top ventilation grille for passive convection heat dissipation
• Front panel dedicated terminal zones separated for AC mains input, DC output channels and remote control signal wiring
• Mounting flange brackets integrated on four chassis corners for cabinet wall / rack fixed installation
• Internal EMI shielding partitions between AC input stage and DC output conversion stage to suppress electromagnetic noise
• Integrated internal EMC filter network to comply with industrial radiated and conducted emission standards

Working Principle

1. Universal AC mains input voltage passes through built-in EMC filter and active PFC circuit to correct power factor and stabilize DC bus voltage
2. Resonant switching converter topology converts high-voltage DC bus to multiple isolated low-voltage DC output rails via independent transformer secondary windings
3. Isolated optocoupler feedback circuits continuously monitor each output rail voltage to adjust switching duty cycle and maintain fixed regulated output voltage under variable load conditions
4. Per-channel OVP/OCP circuits continuously sample output voltage and current; hardware protection circuits immediately cut switching operation upon parameter threshold violation
5. Internal thermistor temperature sensor feeds chassis temperature data to control logic; linear power derating activated at temperatures exceeding 50 °C, full thermal shutdown triggered above 65 °C chassis temperature
6. Power good signal output generates digital logic high level only when all DC output rails reach nominal regulated voltage within 100 ms of power-up

Advantage Highlights

1. Multi-isolated multi-output design eliminates requirement for multiple separate single-output power supplies within control cabinets, reducing wiring complexity and space occupation
2. SEMI F47 voltage sag immunity certification enables stable operation in unstable industrial mains power environments
3. High 92% peak conversion efficiency minimizes cabinet heat generation and reduces cooling fan load
4. Automatic short-circuit recovery eliminates maintenance intervention after field wiring short-circuit faults
5. Parallel current-sharing function supports redundant power supply configuration for high-availability safety control systems
6. Remote on/off control enables seamless integration with cabinet emergency stop and safety interlock logic circuits

Applicable Industries

Semiconductor wafer fabrication equipment, process industry safety control cabinets, industrial automation machine control panels, medical analytical instrumentation, railway vehicle auxiliary control systems, marine shipboard electrical control cabinets, aerospace ground test equipment

Installation Requirements

1. Install vertically on cabinet back panel with minimum 150 mm vertical clearance above chassis for convection ventilation
2. AC mains input wiring must use minimum 14 AWG copper conductors with dedicated overcurrent circuit breaker protection
3. Separate AC mains wiring and DC output wiring with minimum 10 cm physical separation to avoid EMI interference
4. Chassis earth terminal must connect directly to cabinet protective earth bar with 12 AWG copper ground cable
5. Cabinet ambient humidity controlled at 5% – 95% non-condensing
6. Avoid installation adjacent to heat-generating components (power contactors, servo drives) to prevent premature thermal derating

Usage Precautions

1. Do not operate continuously above +50 °C ambient temperature; permanent capacitor degradation occurs under sustained high-temperature operation
2. Never connect different DC output rails together; cross-rail short circuit destroys internal isolation transformers irreversibly
3. Disconnect AC mains supply and wait minimum 5 minutes for bulk capacitor discharge before opening chassis cover for maintenance
4. Do not exceed total combined 800 W aggregate output power across all four DC rails simultaneously
5. Do not install in hazardous explosive area environments; no ATEX / IECEx intrinsic safety certification
6. Do not bypass internal protection circuits via external wiring modifications; such alterations void all factory safety certifications and product warranty
7. Annual inspection of ventilation grille to remove dust accumulation and maintain heat dissipation performance
