Piller Power Technology

Power innovation for over 100 years, protecting the world’s most critical infrastructure.

About Piller Power Technology

Piller Power Systems is a global leader in critical power systems with a wide range of technologies designed to meet the needs of businesses across mission-critical industries: data centres, telecommunications, industrial plants and healthcare facilities.

Static UPS Systems

Compact, low-maintenance, silent — ideal for organisations needing high-performance power systems with no moving parts.

Apostar Premium (AP)

100 kVA – 500 kVA

Engineered for industries that require close to 100% uptime, this transformer-less system delivers superior performance. The AP Premium is ideal for protecting demanding modern power-factor loads.

A double-conversion online UPS with high-performance IGBTs at the front-end provides active filtering for a clean, sinusoidal waveform and guarantees optimal power quality. Advanced digital controls and an innovative DC interface extend battery life for long-term performance.

Built for scale, these systems allow incremental capacity expansion without replacing the entire system.

M+ 500 High-Density Modular Static

Up to 10 × 50 kVA / 50 kW hot-swappable modules

A hot-swappable modular design allows quick plug-and-play maintenance, ensuring minimal downtime. Each UPS M+ 500 50 kVA / 50 kW smart module is fully configurable. Suitable for all types of IT workloads including hyperscale, co-location and enterprise environments.

96.7% efficiency at 1.0 output power factor across 380/400/415 V, 0.99 input power factor, and a 40–70 Hz frequency tolerance for forgiving generator operation.

Critical Power Module (CPM) with Flywheel

225 kW – 2.4 MW

A high-efficiency, battery-free backup solution using kinetic-energy flywheel storage instead of batteries, reducing operating cost, footprint and maintenance while meeting the demands of hyperscale data centres.

Greater than 96% efficiency at 25% load, no battery-replacement risk, and easy expansion as load grows.

Rotary UPS Systems

Rotary designs deliver dip protection against power fluctuations, ideal for data centres and other critical environments.

UNIBlock™ V (UB-V) Series

150 kW – 50 MW

For industrial and critical-service applications and stability in microgrid environments, the UB-V Series includes an extended power range, a control platform and self-diagnostics tied into Piller’s predictive-maintenance service. Configurable for renewable and alternative sustainable energy sources.

Battery or flywheel options, co-generation support, bi-directional power flow, and dynamic ride-through across the full load range.

UNIBlock™ UBT+

150 kW – 50 MW

Versatile low- and medium-voltage system with flexible cooling (air or chilled water) and battery- or flywheel-based energy storage. Suitable for both short-term ride-through and long-term bridging applications across industrial and large-data-centre loads.

UNIBlock™ UBTD+ Rotary Diesel UPS

500 kW – 40 MW

Ideal for large-scale industrial and data-centre applications across low- and medium-voltage requirements, offering flexible cooling options and excellent dip protection to ensure stable supply during voltage disturbances.

Other UNIBlock™ options

Containerised UPS systems and water-cooled variants are available for projects with constrained plant-room space or extreme thermal envelopes. Speak to our team about the right configuration for your site.

Static Transfer Switches (STS)

Apotrans STS

25 A – 63 A and 125 A – 1600 A

Thyristor-based automatic switching system that transfers electrical loads between two independent power sources without interruption. Internal redundancy, integrated bypass and isolation switches, and very fast SCR-controlled transfer keep your downstream loads alive through upstream failures.

Ancillary Piller products

Powerbridge™

Battery-free kinetic energy-storage converters. A compact alternative to lead-acid batteries that saves space and maximises power density per unit, with configurable ride-through autonomy.

Ground Power Units (GPUs)

400 Hz power for aircraft during ground operations, used in aviation, marine and industrial sectors. Avionics, lighting and air-conditioning stay live without running engines or APUs.

Frequency Converters

Convert electrical power between 50/60 Hz and 400 Hz for applications in aviation, marine and industrial environments. Microprocessor control with remote monitoring.
