The VRH320 variable wire-wound resistor is now available from UK-based Arcol Resistors. Is suitable for a wide range of applications for voltage and current adjustment including industrial machinery RPM adjustment, instruments, automated control installations, load simulation and educational modelling.

The VRH320 has been ergonomically designed to enable simple and accurate adjustments by use of its top mounted slider. It is encapsulated in an IP20 rated lacquered metal casing which has dimensions of 446mm x 93mm x 160mm.

There are six resistance values available in this range encompassing 10ohm to 10K0hm. Key specifications of the ARCOL VRH320 include a 320VA continual loading with a 640VA overload capability for a period of 15mins. As with all ARCOL products the VRH320 is RoHS compliant, says the company.
