120-30 Series Voltage & Current Sense Monitors

Voltage Sense Monitors

Easy-to-apply, low current using.  Operate on any battery supply from 6 to 30VDC.  Units are field-configurable to allow for an output either when sensed voltage or current is present or when it is not present.  Will drive S&C POK Strobe Light, assorted DC relays (200mA Relay Drive Output) or provide inputs to recorders or other reporting devices.  Contact us for full hook-up details.

DC Voltage Sense Monitor designed to monitor battery output level.  In doing so it, in effect, is checking the presence of commercial power, and the health of both the charger and the battery. Activation point adjustable from 6 to 30VDC, to correspond to remaining battery capacity desired. Yellow LED’s indicate DC Power and Output presence.  Voltage Adjuster (PN:  120-30-18) is available to adjust trigger point to avoid loading or otherwise lowering the monitored battery.

AC Voltage Sense Monitor designed to monitor commercial power from 70VAC to 240VAC. Yellow LED’s indicate DC Power and Output presence.

DC Current Sense Monitors

Non-vital application, low current using (7mA @ 13.6VDC) devices. Operate on any battery supply from 10 to 30VDC.  Units are field-configurable to allow for an output either when sensed current is above the trigger point, or below it.  Will drive S&C POK Strobe Light, assorted DC relays (200mA Relay Drive Output) or provide inputs to recorders or other reporting devices the current draw for which does not exceed 1.0A.  Six current sense options range from 0.01A to 0.06A through 0.33A to 2.0A.  The common power lead for the device being monitored is routed through the Current Sense Monitor.   The voltage of the Alarm output from the 120 Current Sense Unit will closely match the Sense Unit operating power input voltage.  Contact us for full hook-up details.
