Main features

Compact design

Compact design of 48mm width, 172mm height, and 125mm depth (20/30A types)

Contributes to space saving of control cabinets and control boxes.

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.

Abundant functions are available as standard

Standard functions include Soft-Start, Soft-Down, Manual/Auto switch-over, Ramp setting, Output limiter, and Output bias.

Released from the restriction of magnetic flux density of the transformer, the controller has realized downsizing of transformer (optional)

The control function of the primary side of transformer can suppress excessive current generated from momentary power failure on the load (transformer) side.

To control the primary side of the transformer, it is recommended to use a power controller with a protection function for control of primary side of a transformer. This will eliminate the restriction of magnetic flux density of the transformer.

Abundant options

Options like Heater break alarm, Current Limiter Function, and Constant current control can be added.

cUL C22.2 No.14
CE Marking Low Voltage Directive (LVD): EN60947-4-3   EMC Directive: EN60947-4-3

※1: Protection function for control of primary side of transformer

To control the primary side of the transformer, use a power controller with a protection function for control of primary side of a transformer.
The protection function for control 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 control of primary side of a transformer is not provided, excessive current may occur. Please be sure to use a transformer with magnetic flux density 1.25T or less. Please be sure to activate the Soft-Start function.

※2: CE Marking
When the designated noise filter is used, the requirements of CE Marking are met.
The noise filter specified: SOSHIN ELECTRIC CO., LTD. (This filter needs to be arranged by the user.)
