This series of 100W Switching Mode Power Supplies with Current Limiting Control is designed wuth the objectives of high accuracy, compactness and easy portability.

4 digit display LCD of voltage and current for high precision. The slim tower housing makes it ideal for tight work bench. It is light and conviently portable and a collapsible handle. The large and illluminated LCD display provides clear and sharp radings even under dim light. The output power on-off switch allows safe and handy operations.The Tracking OVP (output over voltage protection) ensures a better and tighter protection to voltage sensitive loads. Ithas good line and load regulations, high efficiency and low ripple and nose that are tyical of advanced switching mode power supply.

It meets the CE safety standards EN-61010 for laboratory grade power supply and respective EMC standards.
