Vesda VPS-300US-UL is a kit that pairs one VPS-100US-UL GEN 2 power supply with one VBC-001 battery cabinet, which holds larger standby batteries. The power supply provides 24 VDC operating power with battery backup for VESDA laser detectors, VESDA-E detectors, remote accessories, OSID beam detectors and the VESDA Sensepoint XCL.
It can run a single detector or several units. The built-in charger supervises and maintains the standby batteries and the supply switches over automatically on AC failure. The two 12 VDC, 12 Ah sealed lead-acid batteries (VBT-012) are not included.
