TEC Manufactured
this variable DC. supply to the customers specific requirements. The problem was he needed
the equipment tailored to operate in a unique way. After discussing his particular
requirements with TEC’s design engineers, the DC. ANODISING UNIT was built consisting
of two separate variable supplies in the same cubicle. Each supply was fitted with, on/off
push-buttons, output voltmeters and ammeters. Limit switches were fitted to the Regavolt
shafts to ensure the unit could not be switched on until the Regavolt handle was returned
to the zero position. Upon activation a timer would start and once the pre-set time had
elapsed a buzzer would sound, and continue to sound until the operator returned the
Regavolt to the zero position, automatically shutting off the power supply. To protect the
supply from overloads a shunt fed overload relay connected to the mains supply was
incorporated. The capability to ensure the power supply could not be activated until the
regavolt was in the zero position, and the power supply shut down when the Regavolt was
returned to the zero position, was finally achieved by the use of two limit switches
mounted on each of the Regavolt shafts connected in a make before break configuration.
