WeighStation™ Track Scale FAQs

What are the power requirements for the WeighStation™ Track Scale?

The power requirements for the WeighStation™ Track Scale are as follows:

The Digital Display (WS-21D) Track Scale requires 7 to 9 Volts AC or 9 to 12 Volts DC, and will draw up to 250 mA.

The Meter Display (WS-21M) Track Scale requires 7 to 9 Volts AC or 9 to 12 Volts DC, and will draw up to 50 mA.

You will need to provide a power source of the correct type (AC or DC) and voltage, with at least the current capacity shown. For example, the Radio Shack 9V/300mA AC Adapter (#273-314) works well for either Track Scale as it provides the correct voltage and more current (300 mA) than either scale requires. Simply clip off the modular connector plug and separate and strip the wires.

Warning: Do not exceed 9 Volts AC or 12 Volts DC as this will damage the Track Scale circuit board.

Radio Shack no longer carries the Radio Shack #273-027 AC Adapter cited in previous WeighStation™ Track Scale documentation. Is there an alternative?

Yes, the Radio Shack 9V/300mA AC Adapter (#273-314) has replaced that previous model and has the same electrical specifications.
