CP24 APPLICATION NOTE

Phenomenon: Pulsing/Flashing Luminaires

Under certain circumstances, connecting multiple CP24 luminaires can cause them to pulse on/off or flash. The CP24 Industrial LED Luminaire uses high-efficiency switch mode drivers designed for constant power. When input voltage drops below the nominal range, power is reduced to prevent battery damage and circuit breaker tripping. Over-voltage protection is also integrated for safe operation on mobile plant equipment.

Power vs Voltage Graph

The graph illustrates the relationship between power consumption and input voltage. It shows a 'Constant Power Range' where power output remains high as voltage varies within a specific band (approximately 21V to 35V). Beyond this range, power output decreases, and a 'Typical over voltage cut-off level' is indicated.

Connection Requirements

The CP24 is designed for connection to a low impedance 24VDC source (e.g., battery or power supply) using cables up to 2 meters in length.

For installations with multiple CP24 units connected to a single common cable (e.g., 15m long with 35mm² cross-section), the cable's inductance can create voltage spikes due to high current peaks. These spikes can exceed the driver's cut-off voltage, leading to momentary shutdowns and external observation as light flicker.

The Q factor, defined as the ratio between Impedance at a particular frequency (ωL) and DC resistance (R), is relevant in this scenario. The formula is:

Q = ωL / R

Solutions for Voltage Spikes

To prevent voltage spikes and associated flickering:

Independent Cabling: Connect each CP24 luminaire directly to the battery using independent cables. A 2.5mm² or 4mm² cross-section is sufficient for each luminaire.
Capacitor Bank: Employ a capacitor bank, such as the Coolon CL-7DR-1000-24 (7 Channel DIN Rail Capacitor Bank, 1000µF 24V), to absorb voltage spikes when independent cable extensions are impractical.

Measurement Note

⚠️ A normal voltmeter or multimeter may not detect these voltage peaks because they perform averaging of the input voltage. A Digital Storage Oscilloscope (DSO) is required to accurately observe these voltage peaks.
