{tab Features} 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. Features Autmatic Cross over CV and CC mode Illuminated LCD indications of A, V, Output On-Off,CC and CV 4 digit displays of Volt and Amp meters Voltage and Current Controls Cimpact slim tower housingCollapsible handle Output power on off switch at front panel Natural Convection Tracking OVP(output over voltage protection), ShortCircuit, overload and over temperatire protections Good line, load regulations and low ruppple and noise Rotary encoder control CE approvals var evExternalHTML = 'power-supplies'; {tab Specifications} Specifications Input Voltage...200-240VAC, 50/60Hz~(or on request) Full Load Input Current at 230VAC...0.83A Output Voltage Adjustable Range...1-20VDC Output Current Adjustable Range...0-5A Voltage Regulation Load from 10% to 100% Variation...50mV Line from 180 to 264VAC Variation...20mV Ripple and Noise in r.m.s....5mV Ripple and Noise (peak to peak)...30mV Current Regulation Load from 10% to 100% Variation...20mA Line from 180 to 264VAC Variation...20mA Ripple and Noise (peak to peak)...20mA Switching Operation Frequency...80KHz to 120KHz Power Factor...0.68 Efficiency at Maximum Power...84% Display...4 Digit Volt.
