Function Features

• Working Principle: High-frequency flyback DC-DC switching conversion topology; input wide-range DC voltage filtered and converted to two isolated stabilized DC output channels via high-frequency transformer, with closed-loop feedback voltage regulation circuit to maintain constant output voltage under variable load conditions
• Multi-layer protection mechanism: Overvoltage protection, overcurrent short-circuit protection, over-temperature automatic shutdown recovery
• Dual color LED status indicators: Green LED for 24 V input power OK, secondary green LED for DIAS bus DC output normal
• Automatic load current balance control when multiple DPS001 modules parallel in one DIAS rack
• Low power loss design, high conversion efficiency ≥89% under rated load
• Built-in reverse polarity protection on input terminal, preventing damage from wrong power wiring
• Compact DIN rail modular design, plug-and-play DIAS backplane bus connection without additional wiring

Material Composition

• Outer Housing: Flame-retardant PA66 plastic (UL94 V0 fire rating), light beige industrial standard color
• Internal Transformer Core: High permeability manganese zinc ferrite core
• Power Switching Components: Industrial grade MOSFET power tubes with heat sink aluminum sheet
• PCB Substrate: FR4 high-temperature flame retardant circuit board with tin-lead free plating
• Terminal Block: Copper alloy gold-plated spring clamp terminal for anti-loose wiring

Structural Characteristics

• Standard 35 mm top hat DIN rail snap mounting structure with integrated locking buckle
• Rear gold-plated edge connector directly inserts into DIAS system backplane bus
• Front panel 2-pin spring clamp terminal block for external 24 V DC power input
• Front visible dual LED status window for real-time power status observation
• Internal vertical heat sink layout for natural convection heat dissipation without cooling fan
• Separated isolation barrier between input and output circuits to eliminate cross-interference

Application Scenarios

• Automated packaging machinery DIAS control rack power supply
• Textile spinning, weaving machine distributed control system
• Port overhead crane, gantry crane SIGMATEK DIAS control cabinets
• Plastic injection molding machine old-generation DIAS automation systems
• Food processing assembly line distributed I/O control equipment

Installation Requirements

1. Install on standard 35 mm DIN rail, lock buckle fully engaged to prevent sliding under vibration
2. Maintain vertical installation orientation; avoid upside-down mounting to reduce heat dissipation efficiency
3. Reserved 10 mm vertical gap between adjacent modules for heat convection
4. Input power wire cross-section minimum 0.75 mm² copper wire, tightening torque 0.5 Nm
5. Equipotential grounding wire connected to cabinet earth terminal to suppress EMC interference
6. Do not install in sealed fully enclosed cabinet without ventilation; maximum ambient operating temperature must not exceed 60°C

Operation & Maintenance Precautions

1. Do not connect input voltage exceeding 30 VDC; overvoltage will permanently damage internal switching tubes
2. Short-circuit protection triggers automatic power cut; power cycle after eliminating short-circuit fault to restore operation
3. Regularly clean dust accumulated on heat sink every 6 months in dusty production workshops
4. Avoid installation near high-frequency inverter, welding equipment to prevent strong electromagnetic interference
5. Parallel connection of more than 3 DPS001 modules requires additional external current balancing resistors
6. Replace module immediately if LED indicator flashes abnormally, indicating internal circuit aging failure
