New 3W - 30W DC high-efficiency converters

Now available from PowerPax, Mornsun R3 Series of DC converters covers an output range of 3W to 30W and is designed to have high efficiency characteristics at both low and full load levels to reduce overall energy consumption in line with the latest energy efficiency requirements. Energy conversation is becoming increasingly important in modern electronic systems, as the heart of many systems, the power conversion function needs to evolve to meet such requirements. Considerable design effort has recently been put into ensuring that this new series of converters meets the highest levels of efficiency with full load efficiency up to 90%, low load efficiency up to 78% and no load power consumption as low as 0.12W. A result of these improvements is an increase in product reliability due to the lack of temperature rise at low loads that is often seen with older technologies, says the company. This range features both single and dual output models with single outputs from 3.3VDC - 24VDC and dual outputs in the range ±5V DC - ±24V DC. All outputs feature a start-up time which is typically significantly shorter than competitive converters. These converters feature 4:1 inputs with 9VDC - 36VDC and 18VDC - 75VDC available as standard with input to output isolation in the range 1.5kVDC to 6kVDC. All models feature input under-voltage, output over-voltage, short-circuit and over-current protection. The operating temperature range is -40C to +85C with an MTBF of minimum 100khrs to MIL-HDBK-217F at 25C. All converters in the range are approved to UL/EN60950. This series features PCB mounting DIP packages and in addition optional mounts for chassis and DIN-rail mounting are available. The series is suited to many applications including, but not limited to, data communications, electricity monitoring systems, data acquisition systems, instrumentation and telecommunications.
