Laboratory Grade Power Supply TM With C.C. Control Description 100W switching mode power supplies with current limiting control, is designed with 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 conveniently portable with a collapsible handle. The large and illuminated LCD display provides clear and sharp readings 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. It has good line and load regulations, high efficiency and low ripple & noise that are typical of advanced switching mode power supply. Features: •  •  •  •  •  •  •  •  •  •  •  •  •  Open circuit current limiting setting capability Automatic Cross over CV and CC mode Illuminated LCD indications of A, V, Output On-OFF, CC & CV. 4 digit displays of Volt and Amp meters Coarse & Fine Voltage and Current controls Compact slim tower housing Collapsible handle Output power on off switch at front panel Natural Convection Tracking OVP (output over voltage protection), short circuit, overload and over temperature protections Good line, load regulations and low ripple and noise Rotary encoder control CE approvals Specifications: Input Voltage (Jumper Selection) Full Load Input Current at 230V AC Output Voltage Adjustable Range Output Current Adjustable Range : 200V AC to 240V AC, 50/60Hz : 0.83A : 1V DC to 60V DC : 0.25A to 1.6A Voltage Regulation Load from 10% to 100% Variation Line from 180 to 264V AC Variation Ripple & Noise in r.m.s.
