4.     Buffer circuit are built inside the unit to protect surge on the SCR

5.     Input,output,error indicatiores available on the panel for monitoring purpose

6.     All model with the same physical sizes

7.     Phase angled firing mode

8.     Black firs reardant housing with resin seal

9.     The unit mainly used for resisitive load

Remark:TDD-220T120A,120A multiple inputs,220VAC soure single phase power regulators .220VAC load

Note:You can order SCR only and purchase heatingsink and cooling fans separately or we can sell complete kits with all parts already put together in our plant

Guidelins on the selection and usage of the voltage regulator

1)Currentrating. as a general rule consider using the relay at no more than 50% of its rated current for resistive load such as a heater. lamps etc.

2)Heatsinks must always be installed together with the SSR regardless of the load amps. natural convection cooling might be sufficient in some cases depends on the site situation.force air cooling must be taken into consider  under harsh conditions(contactour sales team for more info)

3)Fast fuse must be installed in the system to protect overload on the SSR

4)Silicon rubber pad or silicon compound must be applied to the bottom of the SSR to help the heat radiation

5)The SCR is 220V/380Vac load type,please choose correct voltage based on your application

6)This item is suitable for resistive load or very small inductive load

7)The screw for the input terminals has to be fastened securely.otherwise extra heat will be generated and accumulated on the screw and result the damage on the SCR

8)Control cabinet should have sufficient air flow,which means air flow in and out

1.  Power supply indicator,this indicator will light as long as connect with power 220VAC or 380VAC

2.  input indicator,this indicator will light as long as connect with 4-20mA input

3.  Output indicator,this indicator will flash if output is activated,the frequency of the flashing indicates the output valve,flash faster means the output is higher,flash in lower frequency means the output is lower

4.  COM-

5.  CON+

6.  Internal 5V input (only used for potentiometer)
