Water-cooled resistor load unit
Description
Example of a customer-specific resistor load unit consisting of 15 resistor groups (liquid-cooled) and 4 variable resistors with AC motor drive. All resistors are switched by contactors, which are controlled via 24 VDC relays. Two stainless steel distributors are installed for connecting the water cooling.
All resistor groups can be individually hydraulically regulated or shut off. The fittings for the cooling circuit are made of stainless steel. The connections for the resistors and the control are made on internal terminals.
Advantages
- compact dimensions
- Water cooling
- AC/DC loads freely configurable
