Name: rail switching power supply Model: HDR-15W/30W (optional) Power: 15W/30W (optional) Voltage: 5V/12V/15V/24V (optional) Voltage adjustable: 10% Applicable temperature: -15~65 Function: Power Transformer Modulation method: Pulse width modulation Connection method: half bridge Features: Newly upgraded HDR model, thinner rail power supply. DR upgrade, thinner, lighter and more stable. Compared with the old DR, this new HDR is more space-saving when installed on the guide rail, and has the same function, but the volume is reduced by 30%. Composition - pure copper transformer, filter capacitor, 4 terminals, anti-interference, stable performance. Laser printing is used on the main body, and the parameters are clearly visible and not easy to wear. High flame retardant shell, front and rear air outlet design, insulation, stability, corrosion resistance, good heat dissipation. Overload, overvoltage, overcurrent, short circuit, undervoltage and other protection functions actively filter risks and improve electricity safety. _x000D_ _x000D_ _x000D_
