Price Industries 019455-112 Controller
The Price Industries 019455-112 is a field-proven SCR Controller Lite designed for precise 3-phase power modulation in commercial HVAC systems. This 10A current capacity unit provides proportional control of electrical loads, specifically for electric duct heaters and air handling units. Unlike standard binary on/off staging, this Silicon Controlled Rectifier utilizes zero cross-switching technology to ensure a soft start, which effectively eliminates damaging power surges and extends the operational life of the heating elements. The solid-state design offers silent operation, replacing noisy mechanical contactors with a proportional modulation system that prevents temperature overshooting and undershooting. Field technicians can integrate the 019455-112 using industry-standard 0-10 VDC, 4-20mA, or 24 VAC pulsed input signals. For advanced discharge air temperature control, the unit features a dedicated port for an optional DAT probe, allowing for automatic setpoints between 65°F and 130°F. The integrated aluminum heat sink ensures stable heat dissipation, making it a reliable OEM replacement part for high-performance terminal units.
Key Benefits for HVAC Contractors- Precise Load Regulation: Delivers proportional modulation for a stable 3-phase output, increasing energy efficiency and occupant comfort.
- Enhanced System Protection: The zero-crossing feature reduces electrical stress by preventing reactive power spikes during startup.
- Flexible Input Compatibility: Supports BAS controller signals including voltage, current, and pulse-width modulation jumpers.
- Silent Switching: Eliminates the mechanical chatter of mercury and magnetic contactors in noise-sensitive environments.
- Compact Form Factor: The "Lite" series configuration is optimized for tight control enclosures and factory control panels.
Is the Price 019455-112 compatible with single-phase heaters?
No, this specific model is a 3-phase SCR controller. For single-phase applications, the 019455-111 is the correct 10A equivalent.
Does this controller require a separate power supply for the circuit board?
Yes, the board requires a 24VAC power input. Ensure the polarity is correctly aligned as specified in the Price Industries manual to prevent board damage.
Can I use a Discharge Air Temperature (DAT) probe with this lite model?
Yes, the SCR Controller Lite 10A 3PH includes a plug-in port for a DAT probe. Connecting the probe automatically switches the unit into DAT control mode.
