Transtronics Battery Voltage UPS™ (BVUPS™)
12V version with power Fail contacts
The Transtronics BVUPS™ protects your investment in
batteries and increases system reliability
- Are your lead-acid batteries prematurely dying a deep discharge death?
- Does it seem silly to have a 12 or 24 volt battery powered UPS powering a 12 or 24 volt power supply?
- Upon loss of DC power from your power supply, the BVUPS™
"bumplessly" transfers your load to battery current. If the duration of the power failure drains the battery to its Use
EndVoltage(UEV), it will disconnect the load from the battery to protect the battery from damage due to deep discharge stress.
- Upon restoration of power, the BVUPS™ recharges your batteries at a controlled rate with power supplied by
your regulated power supply. It then maintains your batteries in a fully charged state.
- With the Power
Fail
(PF)
option the BVUPS™
with can sense the use of battery
current to conditionally close a set of contacts indicating that the
system is on battery power. As the battery runs down, the battery
power is disconnected and the contacts remain closed (NC).
