WWL-LDX |
The WWL-LDX series power supplies have high precision, high stability and perfect protection circuit. Compared to switching mode power supply, it has higher precision, lower ripple, no high frequency radiation disturbance and wider range of applications. It is widely used in electronic parts factories, universities and laboratories for aging and testing of capacitors, relays, transistors, resistors, generators and other electric products
