Description
Honeywell SPS5710-2-LF
Technical Specifications Brand: Honeywell Model: SPS5710-2-LF Input Power: 115/230 VAC selectable DC Output: 5 VDC, ±15 VDC multiple isolated outputs Construction Type: Low fluorine material formulation Mounting: Hot pluggable rack card Operating Temperature: 0°C to +70°C Humidity: 5% to 95% non-condensing Protection Grade: IP20 cabinet mounting
Functional Features Low fluorine PCB and component materials for special industrial environments. Multiple isolated regulated DC output channels for DCS rack electronics. Hot swap function supports online replacement without rack shutdown. Overvoltage, overcurrent and over-temperature fault protection integrated. Front panel LED indicators show power healthy and fault state. Supports parallel redundant power supply configuration. EMI filter reduces mains noise entering DCS control rack.
Application Scenarios Chemical plants with strict material emission requirements, semiconductor factory control systems, pharmaceutical clean room DCS cabinets, petrochemical process control racks.
Performance Parameters Low fluorine material composition maintains stable electrical performance. Low ripple DC output for sensitive analog and digital DCS circuits. Fast voltage regulation response under dynamic load changes. Immediate protection activation when overload or short circuit occurs. Stable continuous long-term operation for 24/7 process control.
Material Composition Front Panel: Low fluorine flame-retardant ABS plastic. PCB: Low fluorine FR4 multilayer printed circuit board with low-fluorine conformal coating. Core Components: Switching power semiconductors, high frequency transformer, low fluorine electrolytic capacitors, control IC, surge protection devices. Back Connector: Gold-plated edge connector for rack backplane.
Structural Features Rack plug-in card design compatible with SPS5710 series rack slots. Front panel with LED indicators and plastic locking latches. Rear gold finger connector transfers multiple DC power rails to rack backplane. Internal shielding structure suppresses switching power noise interference. Side latches secure module in rack slot.
Working Principle AC input power flows through EMI filter and rectifier circuit. High-frequency switching power circuit converts raw rectified voltage to multiple isolated stable DC outputs. DC power is delivered via backplane to all DCS rack modules. Built-in monitoring circuits check voltage, current and temperature continuously. Any fault triggers power cut-off and activates fault LED and alarm signal. Low fluorine material eliminates fluorine-containing compound release under thermal stress.
Installation Requirements Power off DCS rack before inserting module into rack slot. Lock side latches after installation. Connect AC input wiring to module power terminals. Verify current sharing function for redundant dual power configuration. Ensure rack cabinet ventilation system works properly. Measure DC output voltage on backplane after power on.
Usage Notes Wear anti-static wristband during module replacement work. Wait for capacitor discharge before removing module from rack. Do not exceed rated total output power. Check cabinet temperature and dust accumulation regularly. Backup DCS system configuration before power system maintenance.
