Power in a cold climate

Available in standard and low temperature versions, PULS UK has launched two new MiniLine 60W units. As with other PULS power supplies, the ML60s have been teste at temperatures of up to 60°C but what makes the new low-temperature model stand out is its ability to start and deliver full power from -40°C, giving an overall operating range of 100°C.

PULS has developed special circuitry which limits inrush current and obviates the need to use satiable resistors. It says that this means units can operate in extreme conditions without danger. Similar technology has been incorporated in PULS power supplies at the Neumaver Station III research base in Antarctica to power outdoor monitoring equipment, including sunshine detectors and wind measurement devices.
