4 Mechanical & Design: Compact open-frame size (50×28.5×132mm, W×H×D); lightweight (160g max for open frame, 320g max with chassis and cover); SMD (Surface Mount Device) technology for high reliability; convection cooling (no fan required); optional chassis and cover (electric galvanizing steel board); VH (J.S.T.) connector type (as per SCJ1 variant); PCB material CEM3 (1.6mm thickness)

使用场景 APPLICATIONS

1 Industrial Automation: Power supply for PLCs (Programmable Logic Controllers), industrial sensors, actuators, and automation control systems requiring stable 12V DC power.

2 Embedded & IoT Devices: Suitable for space-constrained embedded systems, IoT gateways, and smart device modules.

3 Telecommunication & Networking: Powering small-scale telecom equipment, network switches, access points, and signal repeaters.

4 Test & Measurement Instruments: Supporting test equipment like signal generators, oscilloscopes, and data loggers that need precise 12V power.

5 Consumer Electronics: Used in audio amplifiers, set-top boxes, and other consumer devices with efficient power conversion needs.

6 Space-Limited Applications: Ideal for equipment where installation space is restricted due to its compact form factor

注意事项 PRECAUTIONS

1 Handling Precautions: Avoid twisting or bending the PCB (SMD components are sensitive to mechanical stress); use spacers of at least 8mm length to prevent contact with SMD parts on the back of the PCB.

2 Operational Guidelines: Do not operate in parallel with other power supply models; avoid prolonged overload conditions; a slight sound may occur during pulse loading (this is normal and does not affect performance); derating is required when using the power supply with chassis and cover (refer to derating curves for ambient temperature and mounting position).

3 Installation Requirements: Ensure mounting torque does not exceed 0.6N·m (6.3kgf·cm) for open-frame units; connect the FG (ground) terminal to metal to reduce electromagnetic noise; ambient temperature should be measured 5-10cm away from the unit to avoid heat interference; perform necessary EMC/EMI tests on the end equipment with the power supply installed.

4 Maintenance & Guarantee: Follow the instruction manual for detailed derating guidelines and warranty terms; do not modify the unit without manufacturer approval
