1-phase SCR 120A
详细说明
Single Phase switching power regulator
Features:
1. Load voltage,single phase 24-380VAC(+/-10%)50/60HZ
2. Work with all kinds of input:0-5VDC,0-10VDC,4-20mA,potentiometer
3. Load options:40,75,80,120,150,175,200 amps
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 application6)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 lower4. COM5. CON+
6. Internal 5V input (only used for potentiometer)
