Principle of Operation

For operating electromagnetic drives MS

The thyristor control unit must be used to operate electromagnetic drives. The EMV-compatible control units from JVM^® allow electromagnetic drives to be regulated con-tinuously and without maintenance during operation.

Flexible regulation

Output value can be set for all JVM^® controllers either via potentiometers or via analog signals 0-10V, 0-20 mA or 4-20 mA.

Constant conveying

Accurate feed rates are maintained because the controller constantly monitors and automatically compensates for voltage fluctuations of ±10%.

Useful extensions

The wide choice of additional components, such as coarse/fine controllers, display devices or manual/automatic switching, enables the right solution to be found for every application.

Internal or external fitting

Our thyristor control units are available both as build-in kits in protection class IP21 or in housing versions in IP54 completely wired with switches, monitor lamps and potentiometers.

Perfect monitoring
As a supplement to target value control, the optional JSEN oscillation sensor allows the machine’s actual os-cillation amplitude to be constantly determined and adapted to the target value. Changes in loadings are thus recorded and automatically compensated.

Safe operation
The drive unit is also protected against hazardous knocking operation in case of actual value failure. An analogue output for process displays and a relay con-tact for operating messages for external process control are integrated here in the same way as a diagnostics plug and illuminated display for voltage and controller release.
