 Power Pack EN 70 LC
The high-voltage Power Pack EN 70 LC is a powerful and hard-wearing unit. Its design fulfils all electrical engineering requirements.
The EN 70 LC Power Pack is used in fast-running machines in combination with tandem ionizing bars. It is equipped with two transformers which operates by 180° out of phase and four high-voltage terminals each. Any surface charges which might disrupt production will be removed reliably and effectively using the HAUG ionizing
unit - even at high operating speeds.

The watchdog function integrated into the secondary area serves to indicate any drop
below the corona inception voltage by means
of a flashing LED.

The HAUG System X-2000 coaxial high-voltage plug-and-socket connection offers a unique benefit. The airtight high-voltage plug can be connected to HAUG Power Packs without the need for any tools. The highly flexible coaxially shielded safety cable is used to connect the ionizing unit to the voltage supply source.
Due to its round design, the tandem ionizing bar type EI RD allows a pin-point rotary adjustment to the running direction of the material. The ionizing bar is absolutely safe to touch. Low-wear special electrodes ensure a long service life. The design fulfils the most stringent requirements imposed by the mechanical engineering industry.

Recommendation:
HAUG Power Packs EN 70 and EN 70 LC should be used in combination with tandem ionizing bars mounted above and below the material web. The ionizing bar is suitable for machine speeds up to 150 m/min

Functional principle of a tandem ionizing system
The example given is based on a web speed of v = 900 m/min. The bars are mounted at a distance of 150 mm and designated S1 and S2. These designations are also indicated on the relevant voltage curves. The ionizing effect is indicated for times t1 and t2.
Tandem ionizing bars are also suitable for machine speeds
of > 150 m/min.
