Portable Power Source for WiNRADiO 1000/1500/3000 Series

Overview

The PPS (Portable Power Source) is an add-on option for external models of the 1000/1500/3000 series of WiNRADiO receivers, to provide mains-independent power for field operations.

The PPS is designed to mount directly underneath the receiver and provides power to the DC input jack of the receiver via a short length of cable with the standard concentric plug.

To charge the batteries, the 12 Volt AC/DC adapter supplied with the external receiver may be connected directly to the PPS input jack.

While charging, external power is also available to the receiver, so that the receiver can continue operating. A bicolor LED on the front panel indicates the charging status.

A battery charge test button makes it possible to determine remaining battery charge using a LED bar-graph.

If the battery charge falls to a dangerously low level, the LED indicator will flash. Typically, this will occur within the last 15 minutes of operation.

If external power is not reconnected before the batteries are completely discharged, the PPS will automatically disconnect the battery output, to prevent a complete discharge of the battery cells which might shorten their life.
