The CyberPower HSTP3T20KE in depth

Why choose the HSTP3T20KE

CyberPower HSTP3T20KE 3-Phase online UPS provides long-lasting power backup for data closets, transportation and infrastructure, and emergency systems. With parallel expansion capability, the HSTP3T (3-Phase) Series UPS is ideal for critical applications in server rooms, data centers, industrial factories, and power generation plants that require high capacity, high reliability, and extended runtimes.

Design and battery management

With integrated IGBT technology and intelligent DSP-based control, the UPS produces less input total harmonic distortion (THDi) and achieves higher power efficiency up to 98% in Economy Mode, making it the most efficient UPS in the industry. Higher operating efficiency equates to lowered BTU heat dissipation and lowered idle power consumption, resulting in an operating expense reduction and a lower carbon footprint.

Installation and expansion

The HSTP3T20KE is a tower unit for floor or desk placement. Fit the optional RMCARD205 for SNMP/HTTP network monitoring and scheduled shutdowns with PowerPanel.
