AC Laboratory Power Supply 0 ... 300Vrms 0 ... 4.2A 500VA - DF-S51005
AC Laboratory Power Supplies of the DF-S Series from DSC-Electronics Germany offer a regulated true sine wave output, excellent stability, precision and performance in a compact cabinet.
- Power supply units (voltage / current sources) (509)
The AC Laboratory Power Supply of the DF-S Series offers excellent stability, precision, performance and functionality in a compact cabinet. The ARM architecture-based digital controller provides fast response times and constant output value monitoring, resulting in high stability and accuracy. Equipped with an RS232 port (51XXX models only), the power supply can be controlled via an open protocol, but the front panel also allows easy setting and monitoring of output values in autonomous operation. Designed for laboratory and industrial use, the AC Laboratory Power Supplies of the DF-S Series can be operated completely maintenance-free around the clock and feature a strong overload capacity of 300% for 2s plus 1.5x the maximum rated current for 100ms.
With a clean true sine wave output, these power supplies are perfect for product testing, calibration or as AC voltage stabilisers.
AC Laboratory Power Supplies of the DF-S Series:
– Solid cabinet
– Potential-free output
– True sine wave output
– Wide output frequency range from 45Hz to 250Hz
– Operation as a constant voltage source (CV)
– Digital connection RS232
– Very short command response time of less than 20 ms
