BS 0.4 Current-using equipment with body-contact resistors
In addition to the resistance of the current-consuming equipment,
2200 Ohm 25 W, this module includes the following body-contact resistance values selectable by positioning a connecting plug:
470 Ohm, 100 W / 2.2 kOhm, 17 W / 33 kOhm, 2 W.
The resistor 470 Ohm, 100 W, is protected by a thermostatic
switch. The operation of this switch is indicated by a signal lamp.
