Interlock according to machine guidelines for the AC input of laboratory power supplies

11. January 2022, admin -

The Lock AC option enables the user of our DC sources of the LAB/HP series to disconnect the laboratory power supply from the mains as required, this function can also be integrated into an existing EMERGENCY OFF chain.

There are many applications where an interlock function for the input is required according to machine guidelines. As with the Lock DC option, there are also different performance levels that need to be taken into account, which must be clarified with the customer in advance of each project.

AC sources with 1-phase or 3-phase output

11. January 2022, admin -

The electronic AC sources of the series EAC-S up to 10 kVA and EAC-3S up to 3 times 10 kVA are very well suited for the simulation of worldwide grids, whether 1-phase or 3-phase. Output voltages up to 700 VAC/phase zero, DC voltages up to 1000 VDC and output frequencies up to 2000 Hz are optionally available. Furthermore, all common interfaces are optionally available as well as

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

21. September 2021, admin -

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

21. September 2021, admin -

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.
