Electrical Installation

Electrical installation consists of making the appropriate power and data connections to the

user’s equipment. In some installations, where multiple Panel Readers are located and

operating at the same time, synchronization wiring will be required.

Power Source Requirements

The Panel Reader is supplied with a cable that allows direct connection to an automotive,

truck or marine battery. A 240 volt powers supply is also available as an option. It is

recommended that you use a well charged automotive battery or the recommended 240

supply. This is important because the 240 volt supply is a “linear” regulated type unit rated at

12 VDC output and 3.0 amperes minimum. Some AC power supplies may exhibit excessive

noise that can compromise read range of full duplex (FDX-B) (sheep / small stock) type

transponders. AC power supplies should be rated at 3 millivolts or less output ripple.

Users can purchase the recommended power supply from Allflex. It will be supplied in an

appropriate weather-proof enclosure (IP56). Alternatively, users can purchase their own

linear power supply and have a suitably qualified electrician mount the device into an

appropriate enclosure. The linear supply required is a Condor brand, part number HC12-3.4+.

The part can be purchased directly for a company called RS Components for around Aus$100.

The RS stock number is 383-9435. The unit can be purchased from RS Components over the

phone using a credit card on 1300 656 636.

The Under Voltage Alarm

The circuitry in the control box has been designed to let the user know when battery life is

low. If the voltage falls bellow 11 volts, the red power light on the face of the control box will

start to flash signaling a possible decline in performance.

Note - The Panel Reader does not contain a power on/off switch. When a power source is

connected to the Panel Reader it will commence immediate operation. When powered from a

battery source, be sure to disconnect the battery when the Panel Reader is not in use in order

to conserve battery life.

Note - The Panel Reader is polarity protected against accidental reverse voltage application

and will not be damaged by such. However, reversing the power connections will prevent the

Panel Reader’s operation.
