Product Data Sheet – Ferrotest

Mobile Power Packs

The high-current Ferrotest mobile power packs provide maximum AC magnetising currents from 1000 Amps up to 7100 Amps. The Ferrotest GWH mobile power packs provide both AC and HWDC; they generate test currents from 1050 Amps to 7100 Amps.

All Ferrotest units are provided with the following built-in standard functions: constant current magnetisation, impulse current magnetisation and  demagnetisation. On all units, the test currents are indicated by a digital display and are infinitely adjustable.

Features

Constant current magnetisation
Constant current is initiated upon operating a foot or hand switch. An electronic system regulates the test current from 0 to maximum in approx. 200 ms, which avoids unnecessary peak loading of the mains supply.

Impulse magnetisation
If the impulse operation is selected a sequence of single impulses is produced according to a factory-set on/off duty cycle of (1 s/1 s).

Demagnetisation
After selecting the demagnetisation setting, the test current is regulated from the set maximum value to 0 in approximately 600 ms.
