Master/slave function for laboratory power supplies

08. December 2021, admin -

In master/slave mode, several DC sources of theLAB/HP series are connected via the ETS bus. Commercially available USB type A cables are used to connect the individual units. However, the interface is not a USB interface. The interface has two connections connected in parallel. This makes it easy to connect several units in parallel. If several LAB/HP are connected and switched on

Laboratory power supplies 30 kW in only 3 U

27. October 2021, admin -

The DC - sources of the LAB/HP series have been revised very elaborately and now have an impressive power density of 30 kW in only 3 U. Output voltages up to 2000 VDC are available and the master/slave function allows the output power to be increased up to 1.4 MW.

System integration

In times where own production capacities are rare, we offer our customers the possibility to install the required laboratory power supplies, no matter if AC or DC sources, electronic loads, bidirectional AC or DC sources, combined in a 19" cabinet. In addition, additional functions such as the integration

Particle filters for our laboratory power supplies

In general, laboratory power supplies are designed for laboratories and production lines with a low or no pollution level. However, there are many applications where these requirements for the pollution level are not fulfilled. As a result, dirt enters the units through the air perforations. Dirt then settles in the units and can create conductive connections, which can result in a short-circuit. In the worst case

Passive overvoltage protection (POP option) for DC sources

14. August 2021, admin -

Overvoltage peaks generated by the customer's application can destroy the output circuit of DC sources. In order to protect the output circuit from this error type, we offer a passive overvoltage protection as option POP for our laboratory power supplies of the series LAB/SMP 750 to 2400 W and LAB/HP 3 kW to 63 kW. This overvoltage protection is realised with suppressor diodes.

Sense mode

In the different branches like industry, research, automotive, railway, aerospace, automation and system integration there are many applications where the required laboratory power supply has to be connected to the application via a longer cable. From a technical point of view, this leads to a voltage drop via the power resistor and the voltage applied to the consumer is therefore lower than the output voltage set at the DC source.
