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
Custom Panel Capability
In addition to the pre-engineered and fieldproven
standard control panels presented in
this catalog, Chromalox has over 60 years
of custom power control systems expertise.
Working with world-scale engineering firms,
military shipboard systems and the most
demanding research institutes, Chromalox has
encountered and conquered the challenges of
even the most specialized requirements. This
experience translates to efficient, economical
solutions for virtually any heating and power
control application.
