Battery Voltage UPS™ (BVUPS™)

12V version

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 volt battery powering a 120Vac UPS  to power 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 UEV(Use End Voltage), 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 PF(Power Fail) option the BVUPS™ 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).
  • Made in the USA
