6.  Dielectric strength (voltage isolation): 3500 VRMS 
7.  Suitable loads: Resistive load, inductive load, capacitive load and transformer primary and other loads
8.  No-load consumption: < 5W 
9.  Mechanism: 180 * 130 * 38 mm (length * width * height)                   
10. Working temperature: -20℃ ~ 60℃, relative humidity: ≤ 90%
II. Features
1. Using 32-bit industrial high-speed microprocessor, LED digital tube menu for operation, fully automatic SMD process manufacturing, stable and reliable performance.
2. Overheat protection: when the temperature is over than 75℃, the control board will shut down output to protect the unit.
3. Soft start: when start, the output voltage will gradually increase from zero to the preset voltage to eliminate the impact on the grid and load.
4. Slow shut down: when shut down, the output voltage will gradually decrease from the preset voltage to zero to eliminate the impact on the grid and the load.
5. Support 0-5Vdc、0-10Vdc、0-10mA、4-20mA and other signals, direct connect with all kinds of meters and PLC, it can use potentiometer manual control
6. Max output limit set: It can set the max output voltage limitation, to help manufacturer to prevent device from damage caused by users false operation.
7. It is with automatic phase sequence recognize, with no phase sequence requirements for the power supply of the control board, regulation-free, convenient wiring.
