DEC 50/5 1-Q-EC Amplifier
Operating modes
Digital speed control, open loop speed control or current control can
be selected with built-in DIP switch.
Small design
Robust and compact modular metallic housing offers various
mounting options.
Easy start-up procedure
Plug-in terminal clamp, no extensive adjustment necessary.
All-round functionality
Direction can be set with a logic signal. Motor shaft can be disabled
or slowed down as required. Adjustable maximum current limitation.
Operating status display with red and green LED.
Flexible set value input
Set value input either through internal potentiometer or external
analog voltage. Two preset speeds switchable. Speed ramp can be
adjusted.
Protection circuit
The power amplifier is protected against thermal overload and the
control inputs against overvoltage.
The DEC 50/5 (Digital EC Controller) is a 1-quadrant amplifier for controlling EC motors with Hall sensors with a maximum output of 250 watts.
