SCR (Thyristor) Power Controller
Salient Features:
- Panel mounted Phase Angle Solid State Relay.
- Input-Output opto Isolation 2500 Vrms
- Virtually free from EMI / RFI
- The Load power is Analogue (Proportional) to controller input
- Input Signal LED indicator
- Heat sink ± Din rail mounting
- Inbuilt snubber
- Output to body 4kv isolation
- Adjustable time delay is also given for pre SSR
- Control Range 10% to 90% of line voltage
- Linearity Better Than ±2% of the range
Precautions:
- Used for Resistive load & Transformer Inductive load only
- Do not give DC voltage at 4-20mA input control of PPC otherwise input of PPC will fail
- Phase line voltage should be in range of 230vac ±10% or 440vac±10%
- PPC will work in Star with Neutral, Star without Neutral& Delta Connection
- Heatsink Temperatures should not increase above 70° C
- Use Semiconductor fuse for Short Circuit Protection
- Phase angle varies so that Rth will change so bigger size of Heat sink required
Applications:
- Glass Industries
- Paper Industries
- Biscuit Making Machine
- Laboratory Equipments
- Hot Runner System of Plastic Processing Machine
- Furnace Industries
- Ceramic Industries
- Chapatti Making Machine
- Electroplating Machinery
