(*)Comparison with RKC THV-1 (20A, 30A)

Eliminates the restriction of the magnetic flux density of transformer and realizes miniaturization (Optional)

• Primary side control function of the transformer can suppress excessive current that may arise due to momentary power failure of the load (transformer). To control the primary side of the transformer, use this Primary side control function of the transformer. It will eliminate the restriction of the magnetic flux density.

Capable to detect a heater break of non-linear load

• A maximum of three inflexion points are settable according to the heater characteristics.

*1：Protection function for primary side control of transformer.

To control the primary side of the transformer, it is recommended to use a power controller with a protection function for the primary side control of a transformer. The control function of the primary side of transformer can suppress excessive current generated from momentary power failure on the load (transformer) side.

When the protection function for the primary side control of transformer is not provided, excessive current may occur. Please be sure to use the transformer with magnetic flux density 1.25T or less. Please also be sure to activate the Soft-start function.

*2：CE Marking

Use the designated noise filter to cpmply CE marking.
