PILLER UNIBLOCK™ UBT+ – rotary uninterruptible power supplies (UPS) with motor generator and switching reactor, designed for data centers, industry, healthcare, banking and other critical infrastructure. Suitable for new and existing installations, normal and harsh environments.
Features:
Single unit capacity 500–2700 kW, parallel up to 40 MW
Efficiency up to 97 % when energy storage is connected
Without power capacitors and electric fans; service life of more than 20 years
Voltage drops up to 50 % without disconnection; up to -30 % without storage energy
100 % nonlinear load control and 100 % load surge control; 99 % harmonic isolation
Clears short circuits on the load side itself without using a bypass
Batteries (up to 30 min) or POWERBRIDGE™ flywheel
Low and medium voltage versions; containerized version
