The 4230 Series of SCR Power Control Panels
offers convenient, economical control of resistive
loads and capabilities beyond the smaller,
more compact 4530 series. An additional
46 Standard Options increase the application
flexibility of the 4230 Series. These pre-engineered,
pre-wired panels require only sensor,
load and power supply connections - and
totally eliminate the need to design your panel,
specify and purchase separate components,
and assemble them into a functioning power
control system.
SCR power control efficiently and accurately
proportions power to the resistive heating
load. Unlike traditional contactor control,
SCR’s deliver:
- Reduced Power Cost
- Extended Heater Life
- Less Maintenance
- Improved Process Products
- Stable Process Temperature
- Zero-crossover Distributed Fired SCR (DOT)
with I2T fusing for SCR Protection
- Fan Cooling
- Load Fusing for Up to 16 Circuits
- Shunt Trip Disconnect
- Ammeter and Voltmeter Combination
- Temperature Controller
- Overtemperature Controller with manual reset
- Ground Fault Monitor
- Fused Control Power Transformer
- Manual Disconnect Switch
- Power “ON” Pilot Lamp
- Automatic Shutdown Device for Overtemperature Protection
- Remote Shutdown Interlock Terminals
- Enclosure Heater with Anti-Condensation and Instrument Protection for Ambient Temperatures as low as 0˚F
- Drawings for Record
- Installation and Operation Manual
