|
DESCRIPTION | |
The EX752M is a dual output 300 watt PSU with Multi-Mode capability. This enables it to operate as a dual power supply with two independent and isolated outputs, or as a single power supply of double the power. As a dual, each output provides 0 to 75V at 0 to 2A (mode A). As a single, the output can be selected as either 0 to 75V at 0 to 4A (mode B) or 0 to 150V at 0 to 2A (mode C). In single modes, the unused half of the unit becomes completely inoperative and its displays are blanked. | |
TECHNICAL SPECIFICATIONS | |
OUTPUT Voltage/Current Ranges 2 x (0 to >75V; 0 to >2A) (300W nominal power) Multi-Mode Operation Three modes of operation can be selected via a rotary switch: Mode A: Two independent and isolated outputs (75V/2A each). Mode B: One output of double the current capability (75V/4A). Mode C: One output of double the voltage capability (150V/2A). Output Setting & Control Voltage Setting: By coarse and fine controls. Current Setting: By single logarithmic control. Output Mode: Constant voltage or constant current with automatic cross-over. CC indicator in constant current mode. Output Switch: Electronic, non isolating. Preset voltage and current limit displayed when Output off. Output Performance Ripple & Noise: Typically <2mV rms, <15mV pk-pk (CV mode, 20MHz bandwidth) Load Regulation: Modes A and B - <0?01%; Mode C - <0?1% + 2mV (90% load change) Line Regulation: <0?01% of maximum output for 10% line change. Transient Response: <200?s to within 50mV of setting for a 5% to 95% load change. Temp. Coefficient: Voltage: typically <100ppm/?C. Output Protection Output Protection: Outputs will withstand forward voltages up to 85V/170V. Output Connections Output Terminals: High voltage touch-proof terminals. Terminals can accept standard 4mm plugs, fork terminals and bare wires.
