Using the optional master/slave cards up to 5 identical units can be connected in parallel to provide up to 1000A and 7.5kW. The required output current is actively shared when the units are connected in parallel. Series operation of 2 units is also possible (limited to 600V maximum output).

Each PSU is able to operate independently, so that systems can be reconfigured, expanded or broken up as needs dictate. The modular approach is useful for test houses and research labs who regularly test different sized power devices. Individual units can be used for the day to day testing of multiple small devices, then grouped together for larger projects. 

The diagram shows the possible configurations with 30V and 300V 1.5kW systems. 

The LAB-DSPH allows the user to set the voltage ramp up and ramp down times via the 5 digit front panel display and computer interface. RS-485 and analogue interfaces are provided as standard. Excellent setting and measurement resolution is provided via the 16 bit processors. If isolated analogue control and monitoring is required, this can be achieved using the Isolated Analogue Programming Port, or ATI (all pins of the ATI are isolated from the negative output). This is a factory fitted option which basically enables both 5V and 10V isolated control and monitoring of the power supply.

Free operating software is available with the LAB-DSPH to set and monitor live values. A sequence mode is also provided.

Measuring only 215mm wide and less than 45mm or 90mm high these compact DC Power Supplies can find space on even the most crowded test bench. If you require a rackmounting system, please see the separate LAB-DSP datasheet.

If your test requirement is short term, we have multiple LAB-DSP units in our rental DC source range.

This series of power supplies can be found in a very wide range of market sectors and applications including: Aerospace, telecom, ATE, quality control, chemical processing, water purification, electroplating, sputtering and coating, semiconductor manufacture, burn-in along with general R&D.

A LAB-DSP system was used to power the Técnico Solar Boat team in the Monaco Solar & Electric Boat Challenge.
