PS-320 300 Watt Enclosed Switching Power Supply Description: These enclosed AC to DC switching power supplies provide a practical, reliable, simple, compact & light weight power source for a variety of applications including motors, controllers, automation, robotics & motion control. The PS-320 has two versions available, 24V & 48V (adjustable from 41V to 56V). Both are mechanically identical. Each PS-320 provides a single 1% regulated DC output from zero to the maximum load of 300 Watts. Over voltage, current limit, short circuit & over temperature protection are built in. There are no internal fuses. If the current limit is exceeded, the supply shuts down & attempts to automatically restart. AC power does not need to be removed to recover from an over current condition. They can not be damaged by shorting the outputs. Operation from either 110V or 220V AC line input voltage can be selected with a single switch. The PS-320 is UL certified to verify safe reliable operation. No additional cooling or heat sinking is necessary due to their high efficiency. They operate up to full load in an ambient environment from 0 to 50°C (32 to 122°F) without de-rating, and over a wider temperature range with some de-rating.
