Main features

Digital control provides excellent response and reproducibility

Digital control power controller with a front display and a keypad.

Setting zero for Soft-Start/Soft-Down provides quick response suitable for rapid thermal processes.

Loader communication for data management

Front loader communication port for improved maintainability

Configuration data management software (PROTEM2) is available

Abundant functions are available as standard

Standard functions include External contact input, Soft-Start/Soft-Down, Manual/Auto switch-over, Gradient setting, Output limiter, Output bias, Input-Phase angle proportional/Input-Voltage proportional/Input-Power phase angle switch-over.

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.

This enables the controller to be used with a lamp heater which has large resistance fluctuation by temperature.

Automatic setting of Inflexion points is available.

※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.
