Frequently Asked Questions
Can I use the HLG-320H-C700B to drive dimmable LED arrays for architectural lighting?
Yes. The HLG-320H-C700B delivers 700mA constant current at up to 299.6W with a 1-10V/PWM dimming input, making it suitable for architectural LED installations that require brightness control. The connected LED array's total forward voltage must fall within the 214-428V CC range.
Is the HLG-320H-C700B suitable for dimming long LED strip arrays in a retail display?
It can work for high-voltage LED strip arrays that operate within the 214-428V CC range at 700mA. The B suffix provides a dimming input for scene control or scheduled brightness changes in retail environments. Ensure your strip array's total forward voltage is within the supported range.
Can the HLG-320H-C700B power LED modules in a large outdoor sign with scheduled dimming?
Yes. At 299.6W and 700mA constant current, it can drive substantial LED sign arrays whose series voltage falls within 214-428V. The dimming input enables day/night brightness scheduling. Its IP65 rating protects against dust and rain in sheltered outdoor locations. For fully exposed sites, consider the IP67-rated HLG-320H-C700DA.
How does the HLG-320H-C700B differ from the HLG-320H-C700A and C700AB?
The -C700B provides a 1-10V/PWM dimming input but no output adjustment potentiometer. The -C700A has a potentiometer for current adjustment but no dimming input. The -C700AB combines both features. All three share the same 299.6W, 700mA, 214-428V CC specs and IP65 rating. Choose the B if you need dimming but not manual current trimming.
How many LEDs can I connect in series to the HLG-320H-C700B?
The count depends on each LED's forward voltage. This driver outputs 700mA constant current across a CC voltage range of 214-428V, which supports very long series strings. Sum your LEDs' forward voltages and confirm the total falls within that range. The high voltage range makes it especially suited for applications with many LEDs in series.
Can the HLG-320H-C700B handle cold-weather outdoor installations?
Yes. It operates from -40°C to +85°C, making it suitable for cold climates including unheated outdoor enclosures. The IP65 rating protects against dust and water jets. The aluminium casing helps with heat dissipation during warmer periods while the wide operating range ensures reliable startup in freezing conditions.
