6.0 POWER SUPPLY V10
Figure 8 - Power Supply Connections
6.1 Introduction
The V10 power supply can operate from any voltage between 20-300Vdc or 55-275Vac
(45-65Hz). It is therefore possible to power the M87x with AC or DC station power or an
auxiliary VT, provided the voltage remains above 55Vac or 20Vdc. The power supply
creates 3.3V, 5V, and +/-12Vdc outputs and consists of an isolated flyback converter that
provides at least 12.5W of output power at 3.3Vdc and/or 5Vdc.
6.2 Features

25W minimum output power from the combined 5V and 3.3V supplies.

+/-12Vdc capable of delivering up to 500mA.

Standard cPCI power connector.

Removable terminal block accepts bare wire or terminal lugs.

5Vdc and 3.3Vdc power indicator LEDs.
