Features

Phase control: continuous intersection control, stable output, ammeter does not flutter, but half wave every cycle will generate harmonics.
Use load: constant impedance load, variable impedance load, IR lamp.
Zero-position control: Distributed zero-position control, minimum resolution is 1Hz, will not generate harmonics, and the ammeter appears jittering when output.
Applicable load: constant impedance load.

Precautions

Main circuit is 3-phase 4-wire input, no phase sequence is required.
SCR is high current product, please be sure to lock the (R.S.T) and (U.V.W) terminals, otherwise the terminals will heat up, causing e SCR burn out.
SCR has a built-in fast fuse for over current and short circuit protection. If the fuse is blown, be sure to replace it with fuse of the same specification. Be careful not to increase amperage of the fuse at will.
When using 3-phase load Y type connection, the center point of Y must be connected to zero line. If the center line of Y is not connected to zero line, the 3-phase load needs to be relatively balanced.
When using the module, if load power is high or heat dissipation conditions are not good, please consider air cooling.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
