Half Bridge resonant SMPS with SINGLE rail output voltage and two independent auxilliary isolated outputs. It is capable to deliver 800W continuous and 1000W peak power. The stock available output voltages are 36V, 48V, 60V and 72V. It uses zero-voltage switching half bridge resonant topology. The main advantage is lower size and cost compared with a similar regulated SMPS and better efficiency, up to 95% compared with the regulated SMPS's due to the fact that the transistors are soft-switched, and the current through the switches has sinusoidal shape, and there are no output inductors. The SMPS features overcurrent protection which limit the output current at about 125% of the nominal power, about 1000W. The mains supply voltage can be set for either 110V or 230V. This power supply is only suitable for BTL amplifiers, which use single rail supply, or other applications where a single output of 36V, 48V, 60V or 72V is required. It is not suitable for Class AB or class D amplifiers which are configured in Single Ended opperation mode, for these amplifiers, consider using the SMPS800RE which is almost identicat except the output section. In addition to the main output voltage, two auxiliary regulated voltages are available, with the following voltages 2x5V at 500mA 2x12V at 200mA or 2x15V at 400mA. Any combination of two aux. voltages is possible when custom voltage is chosed. The auxiliary voltages are independent and galvanically isolated from the main output voltages, and each Aux. GND can be referenced at any main output potential. The Power Supply has on-board Mains IEC Power Connector, which allows easier installation without using other mains cables than the ones for the mains switch. For operation inside a tight case, an optional variable speed cooling fan is available, which should be used when the Power Supply delivers high power for long periods of time. The overall size of the Power Supply is 150mm long, 100mm wide and 38mm tall, which makes it suitable to be used in 1 RU cases, with an overall height of maximum 43mm including spacers.
Pay attention when order this power supply as it is not SMPS800RE compatible and the output voltage cannot be changed from Single to Dual !!!
