Power Supplies

Triamec TP-Netzteile

TP series devices are designed for TSD series servo drives and fulfil five tasks:

  • Rectification and smoothing of the AC input voltage
  • Line Filter Class C3
  • Brake chopper with internal or optional external resistor
  • Inrush current limiter
  • Monitoring of the input phases (3PH Variant)

A 3-phase AC input is recommended. A 1-phase AC input is also possible, but leads to increased ripple on the DC-Bus at medium to high loads. Alternatively, a DC supply can be used, see input voltages in the table below.

Brake Resistor Variants

NO Version with internal breaking resistor
BRK Version for external breaking resistor


Input Monitoring Variants

NO DC and AC Input
3PH Only three phase AC with phase monitoring


Configuration Examples:

TP80-NO-NO  Accepts DC, single phase AC and three phase AC input

TP80-NO-3PH Accepts only three phase AC input

TP80-BRK-3PH Requires an external brake resistor and accepts only three phase AC
