Power supply 3-phase, 48 V dc Dimension X Series

Output current of 20 A
Up to 96% efficiency
Semi Regulated
Replaces linear transformers
Very high short-circuit current

Product description

Dimension X series is a series of semi-regulated power supplies. A so-called semi-controlled unit means that the output voltage is regulated within the specified input voltage range. Outside this range decreases / increases the output voltage compared to the input voltage.
The unit has a bonus effect of 25% (25 A) to cope with high starting currents, as well as a very high short-circuit current enables safe trips for eg MCB. The unit leaves up to 90 A at 100 ms. Lasts short circuit longer than 100 ms, the unit shuts off automatically. See chart below for details. Recovery occurs in the front, or by disconnecting the primary voltage.

A yellow LED indicates the status and warns of the following errors; phase failure, over-temperature and high load current.
The unit has a low weight (1.4 kg), no inrush current and active transient filter that protects the secondary side from transients on the primary side.
Typical applications include motors, solenoids or other "power hungry" loads that do not have requirements for accurate voltage regulation. X series are a great alternative to traditional transformers. With lower energy costs and easier installation, along with an attractive price concept means a low total cost.

We recommend free space of 40 mm above and 20 mm under the power supply, and 5 mm at the sides. (if neighbouring products are counted as a heat source spacing of 15 mm is recommended).
