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.
