Addition to the family

Baden-Baden, 17. July 2018

The bidirectional 15 kW DC power supply by Dutch manufacturer Delta Elektronika is now available in two versions.

To complement the already-existing model with ouput values of max. 500 V and max. ± 90 A, a version with max. 1,500 V and max. ± 30 A is now  available. “With this model variant we are meeting the great demand for high voltage power supplies for inverter tests in the solar field and also in the automotive sector to test components in electrical vehicles.  The new variant is equally attractive thanks to its outstanding technical values, which set benchmarks in the market. We should mention its high control accuracy of 10 mV (CV) and its dynamic behaviour, for instance with load changes, as well as its high programming speed of 2.8 ms (fall time 90 – 10 %)”, says Stefan Dehn, Head of Sales at Schulz-Electronic.

The source-sink system is a precise bidirectional high voltage power supply with virtually loss-free mains feedback. An optional master-slave interface enables several devices to be connected in parallel to increase the power rating. This simplifies programming as all devices together behave as if they were one device. Their speed of reaction makes these power supplies highly suitable for simulating battery systems or photovoltaic systems.

The 3-phase wide range input with active PFC for voltages from 342 - 528 VAC and 48-62 Hz enables the devices to be operated in any power grids in the world. The power supply sets benchmarks in EMC and stays well below the values required for EN 55022 Class B. In both operating modes, source and sink, efficiency is higher than 95 %. Thus these power giants dissipate very little heat and are pleasantly quiet.

Dehn sums up: “These power supplies are perfect all-rounders for demanding applications in all areas of industry and science”.
