Power pack EN 70 / EN 70 LC / EN 70 RLC
The high-voltage power pack EN 70 / LC / RLC is a powerful and hard-wearing unit. Its design fulfils all electrical engineering requirements. The EN 70 / LC / RLC 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 (see ill. 1).
The power pack EN 70 RLC has two additionally relay contacts for fault signals.
The watchdog function integrated into the secondary area serves to indicate any drop below the corona inception voltage by means of a flashing LED (ill. 3).
The HAUG System X-2000 coaxial high-voltage plug-and-socket connection (ill. 2) offers a unique benefit. The airtight high-voltage plug can be connected to HAUG power packs without 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 bars El RD / El VD / El HRD allow a pin-point rotary adjustment to the running direction of the material. The ionizing bars are 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.

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 300 mm and designated and S2. These designations are also indicated on the relevant voltage curves. The ionizing effect is indicated for times t1 and f2. Tandem ionizing bars are also suitable for machine speeds of > 150 m/min.
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 (see illustration).
