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.

Sense mode

25. May 2021, admin -

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.

Galvanically isolated analog interface

12. April 2021, admin -

A galvanically isolated analog interface is mainly used in automated systems for test procedures, production processes and stand-alone systems. Since the systems are controlled by PLCs, an analogue interface with galvanic isolation and a control level of 0-10 V or 0-5 V is ideal for this application.

Decoupling diode serial for DC sources

12. April 2021, admin -

Decoupling diodes are used to protect against unwanted reverse voltage into the laboratory power supply and to protect against overvoltages that do not reach 150% of the maximum output voltage. Semiconductor diodes are connected in series to the output. This feature avoids energy being discharged into the output circuit when batteries are connected to the DC source.

Freewheeling diode for DC - sources

16. February 2021, admin -

 Free-wheeling diodes are used for protection against overvoltage when an inductive DC load (e.g. electric motor, relay coil, solenoid) is switched off. For this purpose, semiconductor diodes are connected in parallel to inductive DC loads so that they are stressed by the supply voltage in the reverse direction.

Option High Speed for DC sources

06. February 2021, admin -

Increasingly, fast test signals are required in connection with high power. Whether for the simulation of on-board voltages or for the generation of interference pulses. By reducing the output capacitance while using film capacitors, the rise and fall time is reduced by a factor of 10 compared to the standard value.
