Description
The Hytronik HC419VRC/R is a high-frequency (5.8GHz microwave) occupancy detector designed for indoor high-bay applications like warehouses and storage rooms. It provides automated tri-level dimming control via a 1-10V interface, featuring a zero-crossing detection circuit to minimize in-rush current and extend relay life.
Technical Specifications
- Operating Voltage: 120-277VAC, 50/60Hz.
- Load Rating (Capacitive): 400W @ 120VAC; 1000W @ 277VAC.
- Detection Range: Max 16m x 15m (D x H) with a 30° to 150° angle.
- Standby Power: < 0.5W.
- Operating Temp: -20°C to +60°C.
- IP Rating: IP20.
Key Functionality
- Tri-Level Control (Corridor Function): Manages three light levels (100%, dimmed, and off) based on two selectable waiting periods: hold-time and standby period.
- Synchronisation: Up to 10 units can be connected in parallel via "SYNC" terminals; if one sensor triggers, the entire group activates.
- Daylight Monitoring: Features a 24-hour "smart photocell" function that can maintain dimming levels at night and switch off completely when natural light exceeds the threshold.
- Manual Override & Semi-Auto Mode: Supports push-switch input for manual on/off, brightness adjustment (10%–100%), or absence detection mode.
Configuration & Controls
- Settings can be adjusted via onboard DIP switches or the HRC-05 remote control (supplied).
- Hold-time: 5s to 30min14.
- Standby Period: 0s, 10s to 1h, or +∞ (permanent dimming).
- Standby Dimming: 10%, 20%, or 30%
- Daylight Threshold: 2–50 lux or disabled
