High-frequency converters
Electronic high-frequency converter.
The HFO-E is an electronic converter: strong output with none of the rotating parts that eventually wear, so there is less to go wrong. It is noticeably lighter than a traditional converter, quiet in use, and protects the operator through galvanic isolation, automatic overload shut-off and restart, and phase protection. Automatic power control and up to four poker outlets make it straightforward to use, even in rough site conditions.
| Product type | Power output (kVA) | Prim. voltage (V/ph/Hz) | Sec. amperage (A) | Sec. voltage (V/ph/Hz) | Outlets | Weight (kg) |
|---|---|---|---|---|---|---|
| HFO-E 1.8 | 1.8 | 230/1/50 | 25 | 42/3/200 | 2 | 16 |
| HFO-E 2.5 | 2.5 | 230/1/50 | 35 | 42/3/200 | 2 | 18 |
| HFO-E 3.6 | 3.6 | 400/3/50 | 50 | 42/3/200 | 3 | 26 |
| HFO-E 5.3 | 5.3 | 400/3/50 | 75 | 42/3/200 | 4 | 31 |

Comparison
Each machine in this category is designed for the same application, but optimized for different power options, site conditions, and user requirements.
Tell us what you do — we'll recommend the right model, no obligation.
The HFO-E has no rotating parts that wear over time — unlike the magnet-driven HFO — so there's less to go wrong, and at 16 to 31 kg it's noticeably lighter than a comparable traditional converter, plus quieter in use.
Through galvanic isolation, automatic overload shut-off and restart, and phase protection. It ranges from the HFO-E 1.8 (1.8 kVA, 2 outlets) up to the HFO-E 5.3 (5.3 kVA, 4 outlets, 75 A secondary current), so protection scales with the number of pokers you're running.
Every Lievers machine comes with a one-year warranty. Register your machine and you get a second year on top — two years of cover in total.
Lievers machines are backed by a network of local service points with spare parts on hand, so maintenance and repairs stay close to the job. Get in touch and we'll point you to the nearest one.
