Pentpak 427 high frequency power pack
The Pentpak 427 high frequency power pack is designed to a new and unique concept. The
electronic units are especially designed for the Pentpak 427 and the power pack is one of the most
compact designs on the market. It offers outstanding performance combined with reliability, safety
and ease of handling.
New regulations for the design of machines and the specifications for their inherent safety have
been the ruling parameters in the design and development of this power pack.
Design, function and special features of the Pentpak 427.
•
For optimum safety and manoeuvrability all functions are controlled through a remote control
unit. The operator can therefore always be in the safest and best possible position and still have
full control of the machine.
•
The remote control system contributes to a high level of safety. All functions are reset
automatically when the power supply is disconnected, or when any of the Emergency Stop-
buttons are depressed.
The blade, if in rotation, and in a cut, will continue to rotate because of its
inertia, but will coast to a stop after a few seconds. If the blade is rotating and not in a cut, it will
take longer before the blade stops.
No functions remain after the power pack has been shut off.
At every restart the power pack starts from the same initial mode with all functions reset.
•
The converter is water cooled which provides excellent cooling of the transistor power modules in
the frequency inverter.
•
If the power pack is run using an inadequate supply of cooling water, it is still protected from
overheating by means of a temperature sensing device inside the power pack.
•
The Pentpak 427 is compact and weighs only 26
kg
, still it can drive the electric motor with a
continuous output of 27 kW.
•
The power pack has a high overall efficiency factor and at 400 V a 32 Amp delay fuse will be
enough to run the power pack and motor at their maximum rated output. We recommend to use a
40 Amp fuse if possible.
•
All electrical and electronic equipment is protected under covers and can not easily be tampered
with. The only device that can be operated is the (green) start and emergency stop buttons.
