DEC Module 50/5 1-Q-EC Amplifier Operating modes Digital speed control or open loop speed control operation can be preset by a digital signal. Excellent price/performance ratio Reasonably priced 1-Q-EC amplifier optimised for OEM applications in small appliances. OEM Module Miniaturized open electronics board. Connector arrays arranged in a 2.54 mm (0.1) pattern support easy connectivity and integration into the motherboard. Functionality Direction of rotation preset by a digital signal. The motor shaft can be enabled or disabled. Adjustable maximum current limitation. Set value speed input through external analog voltage. Speed can be monitored through the speed monitor output. Status indicator with Ready-Output. Protection circuit The power amplifier is protected against thermal overload and the control inputs against overvoltage. The DEC Module 50/5 (Digital EC Controller) is a 1-quadrant amplifier Technical data page 299 for controlling EC motors with Hall sensors with a maximum output of Dimensions and connections page 301 250 watts. 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.
