DC power specification

• Voltage 24 V to 80 V
• Current input to 10 A

The UCC T3 controller requires 30 W of power to support the controller functions integrated into the unit. This must be factored into the power supply used.

CAUTION: For ambient temperatures between 40 °C and 50 °C, the maximum input power should be 400 W.

CAUTION: UCC T3 is not recommended for use in ambient temperatures above 50 °C.

Regenerating loads

The UCC T3 controller can be attached to motors that cause a regeneration of voltage during the deceleration stage of machine motion. The system integrator must ensure that the power supply used in the installation will permit any regenerative voltage to be accepted without failure.

NOTE: If the power supply is not able to withstand this regenerative voltage from the motors, then a suitable diode must be wired in series with the positive supply to isolate this event.
