Control unit UC253C

The UC250 power control unit can work with all types of attachments (it is not possible to operate with two attachments at the same time). The control unit contains an automatic feedback circuit, which protects constant revolutions under various working conditions. The device is equipped with the following safety features: 1) a fuse to protect against a short circuit of the power supply or against an abnormal electric current in the primary circuit 2) thermal fuse located in the transformer to protect against overheating 3) a temperature sensor, which eventually switches off the current supply 4) an electronic interrupting circuit that temporarily stops the current supply in case of extreme load on the attachment Dust-free system for overall regulation. As an accessory, it is possible to order a foot pedal type VC10 (= foot controller) or FS18 (= foot switch). The electronic circuit for quick stop allows the attachment to stop as soon as the operator takes his foot off the foot pedal or turns off the mains switch. Input AC230V 50/60 Hz 30VA, Output DC voltage 3-30V 0.3A x 2.
