Triol
AT27 ED

Reliable low voltage industrial drives for pumps, fans, conveyors, and more.

Pure Sinusoidal Output & Motor-Friendly Design

Multi-level topology + built-in sine filter delivers clean power (THDu ≤ 5%, dV/dt < 1000 V/µs), eliminating the need for extra output filters or step-up transformers, works with any motor (new, old, induction, PMM, synchronous).

Compact Footprint & Easy Service

One-sided maintenance, wall-mountable design, and outstanding power density (up to 158 kW/m²) make it ideal for space-constrained installations while keeping deployment and service time minimal.

Ultra-High Power Quality from the Grid Side

Built-in multi-winding phase-shifting transformer + 18–72 pulse rectifier gives power factor ≥ 0.96 and THDi < 5% across the entire range, fully IEEE 519 compliant without capacitors or additional input filters.

AT27 ED UL

The AT27 ED UL is a compact and reliable medium-voltage drive, UL certified to meet strict industrial safety and performance standards. It ensures protection from electrical faults, efficient thermal control, and minimal maintenance-ideal for demanding applications in oil and gas, utilities, and infrastructure.
