The high frequency AC power supply DF-CM series is a high frequency modification of the proven alternating current-industrial power supplies of the DF-C series and offers excellent stability, precision, performance and functionality for operation at high frequencies. Designed for high performance laboratory and industrial applications, these power supplies are completely maintenance free, even in 24/7 continuous operation. The ARM architecture-based digital controller provides fast response times and constant output value monitoring, resulting in high stability and accuracy. Equipped with optional RS232 or RS485 port with Modbus RTU support, this high frequency AC power supply can be controlled externally, but the front panel allows easy setting and monitoring of output values even in autonomous operation. Switchable low-voltage high-current (LV 0 ... 150Vrms) or high-voltage low-current (FS 0 ... 300Vrms) ranges provide maximum flexibility, while the standard frequency is adjustable over a wide range of 350Hz ... 450Hz and can be extended to 200Hz ... 2500Hz if desired.
With a clean true sine wave output, these power supplies are perfect for product testing, calibration or as AC voltage stabilisers.
Advantages of the high-frequency AC power supply units of the DF-CM series:
- Solid free standing rackcabinet
- Floating output
- True sine wave output
- Wide output frequency range
- Operation as constant voltage source (CV)
- Optional digital connection RS232 or RS485 with Modbus RTU support
- Very short command response time of less than 20 ms

[U] Ext. control signal U
A control terminal for external control of the output voltage, available in different versions for different control systems (0 ... 5V / 0 ... 10V / 4 ... 20mA).
[F] Ext. analog feedback U
Feedback output for external control of the output voltage actual value, available in different versions for different control systems (0 ... 5V / 0 ... 10V / 4 ... 20mA).
[G] Ext. analog feedback I
Feedback output for external control of the actual output current value, available in different versions for different control systems (0 ... 5V / 0 ... 10V / 4 ... 20mA).
[A] Ext. output interlock
Allows remote control of the status of the output power (on/off), executed as open/closed loop (open = output off / closed = output on).
[D] Digital connection
Digital connection for setting and reading out the device parameters in real time.
[O] Output configuration
Selection of the output configuration (floating, positive ground, negative ground, ...).
