Frequency 48Hz–62Hz Inrush current 5.8A @ 400Vac input. Isolation I/P to O/P: 3750V rms (8mm creepage), I/P – Case: 2500V rms, O/P – Case: 600VDC OUTPUT Output voltage See table. Output voltage adjustment 0%–100% Output current See table. Output current adjustment 0%–100% Resolution 0.03% voltage and current control with 10 turn potentiometers. Efficiency 87%–91% Switching frequency 100kHz Thermal protection Yes Programming Analogue Programming of voltage and current by 0-5V. IEEE488 programming with external interface controller PSC44M Programming speed See table Master/Slave operation Parallel and series operation with equal current and voltage sharing. In this way two or more SMunits can together be used as one high power unit. Voltage and current of the units is controlled by the master (by potentiometers or by programming). Series operation up to 600V Metering Digital meters standard Indicators CV/CC mode, OVP triggered LEDs Overvoltage protection Yes. Trip range user adjustable 0%–115% of V max. Overload protection Yes Short Circuit protection Yes Temperature coefficient CV: 10x10-6 to 35x10-6 / °C, CC: 20x10-6 to 60x10-6 / °C. The CV/CC regulated power supplies are very suitable for battery charging. Ask for the special datasheet “BATTERY CHARGING WITH SM-series POWER SUPPLIES”. This datasheet contains information about protective measures against accidental battery reversing. Load regulation 0%–100% load see table ENVIRONMENTAL Line regulation Line ±10% – see table Operating temperature -20°C to 50°C Ripple & Noise See table Cooling Stability CV: 2.10-5 to 4.10-5, CC: 3.10-5 to 10.10-5 Low noise blower, fan speed adapts to temperature of internal heatsink.
