RC4000 ACU Boardset

2.1.2.1.1 J1 - AC Power Input

Designation
J1 "AC Power"
The Power/Drive board may be purchased with optional 300 or 500 Watt power supply cards. If a power
supply card is present, AC input power is supplied to connector J1. If external DC power is to be supplied
(see section 2.1.2.1.6), leave connector J1 open.
The power supply cards can automatically accommodate AC input between 85 to 265 VAC and between
47 to 63 Hz. The power supply card will convert the AC input into 24 VDC power for use by the drive
section and for powering the other boardset cards.
Typical sizing of the power supply card will mainly be a function of motor drive requirements. The
following power requirements for the boardset cards and external sensors will also need to be
considered:
Component
Computing/Interface Board
LCD (if present)
Drive Board (excluding motor drive power)
Options Board
GPS Receiver
IP Interface
NOTE: All system (boardset components, motors, sensors, etc.) power requirements need to be
considered when sizing power supply.
A wire size appropriate for the total system power should be used. It is also recommended that a "slow
blow" fuse of appropriate size (typically 3 A.) be placed inline to the AC input.
