UPS-P91-1500

Item Number: 1000356

Online UPS, 1500 VA / 1450 W, 120V

  • Online double-conversion UPS with pure sinewave output
  • Provides a high, near-unity output power factor
  • Wide input voltage range (55–150 VAC)
  • Tower, wall, 2-post, and 4-post rack mounting configurations
  • Multiple communication interfaces (RS232, USB, and optional Web/SNMP, Modbus, Relay/dry contact cards)
  • Supports hot swappable EBM modules for extended backup time
  • Maintenance bypass - an optional XBDM bypass module enables the P91 to be replaced or serviced without interruption of power to critical loads

The UPS-P91-1500 is an online double-conversion UPS designed for mission-critical applications that demand clean, continuous, and isolated power. Its near-unity power factor maximizes usable wattage, while the flexible 2U rack/tower design fits seamlessly into PAGA controllers, intercom systems, IP telephony, navigation equipment, monitoring systems, and critical automation. The UPS-P91-1500 offers scalable runtime through optional external battery modules, supported by a high-capacity charger delivering up to 8 A for rapid recharge of multiple battery packs. With hot-swappable batteries, optional maintenance bypass, ECO-mode efficiency up to 98%, and broad communication support - including USB, RS-232, and optional Web/SNMP or Modbus cards - the UPS-P91-1500 ensures reliable operation and easy integration into modern monitoring systems.

UPS-P91-1500 Runtime overview (updated in December 2025):

  • 1450 W / 3 min -> no additional battery module
  • 900 W / 30 min -> with one additional UPS-P91-BP36 battery module
  • 1450 W / 33min -> with two additional UPS-P91-BP36 battery modules

Note: The UPS-P91-1500 UPS supports up to seven external battery modules.
