* Optional

AC Laboratory Power Supplies of the DF-S series provide excellent stability, precision, performance and functionality in a compact laboratory power supply. The ARM microprocessor-based advanced digital controller provides fast response times and constant output monitoring, resulting in high stability and accuracy. Partly equipped with RS232 connection (51XXX models), the power supply can be controlled via an open protocol, the front panel also allows easy setting and monitoring of the output values ​​even in autonomous operation. Designed for laboratory and industrial use, AC power supplies of the DF-S series can also be operated 24/7 completely maintenance free and feature a strong overpower capacity of 300% for 2s plus 1.5x the maximum rated current for 100ms.

Options

The following is a brief description of the possible additional options for laboratory power supplies of the DF-S series. A detailed description can be found in the datasheet of the series, should you have any questions contact our support during our opening hours via the live chat or by e-mail and we will gladly assist you.

[A] Interlock
For security reasons, the power supply output can be enabled / stays enabled only as long as the interlock loop is closed.
