25-1000-UM 3
Product Overview
The Electroswitch 25-1000 panel mount Battery Monitor is a breakthrough in battery
monitoring and ground fault detection. This highly accurate panel mount instrument is
powered by the same battery it monitors. It displays charging voltage, ripple voltage,
ripple current (with optional current probe, 25-1100-H1) positive/negative ground faults
and high impedance faults based on ripple voltage and ripple current.
The alarm outputs are designed with form C relay contacts and can indicate +bus / -bus
leakage, ground shorts, over/under voltage, high ripple voltage, low ripple current, loss
of AC voltage to the charger and high impedance due to corrosion buildup.
Also included, an additional feature that generates a pulse through the ground fault path
enabling the operator to locate the exact location of the short circuit using the optional
model 25-1100-GF handheld ground fault detector.
All alarm set points and system functions are stored in on-board non-volatile memory
and will not be lost even when power goes down. Fail safe operation is provided by relay
contact when power is lost. The instrument also provides a time delay alarm feature
that allows the operator to delay alarms up to 60 seconds preventing false alarm
indications. The 25-1000 Battery Monitor supports DNP3 or Modbus serial
communication protocols over a RS-485 data line. Industry standard baud rates up to
19.2K. Additionally the instrument provides 4-20mA or 0-1mA analog outputs.
