Overvoltage protection SM1540-D: 0-17V, SM7020-D: 0-80V, SM3004-D: 0-350V. Overload protection Yes Short circuit protection Yes Temperature coefficient CV: 5x10-5 per °C, CC: 1x10-4 per °C. Load regulation 0%–100% load see table. Line regulation Line ±10% – see table. Ripple & Noise See table. Stability Efficiency 87%–89% . Switching frequency 100kHz Thermal protection Yes Programming Analogue Programming of voltage and current by 0-5V. 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 MTBF 500,000hrs BATTERY CHARGING The CV/CC regulated power supplies are 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.
