Description

HLG-320H series is a 320W AC/DC LED driver featuring the dual mode constant voltage and constant current output. HLG-320H operates from 90 ~ 305VAC and offers models with different rated voltage ranging between 12V and 54V.
Thanks to the high efficiency up to 94%, with the fanless design, the entire series is able to operate for -40°C ~ +90°C case temperature under free air convection.
The design of metal housing and IP67/P65 ingress protection level allows this series to fit both indoor and outdoor applications.
HLG-320H is equipped with various function options, such as dimming methodologies, so as to provide the optimal design flexibility for LED lighting system.

SPECIFICATION

NOTE

All parameters NOT specially mentioned are measured at 230VAC input, rated current, and 25℃ of ambient temperature.
Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
Tolerance: includes set up tolerance, line regulation, and load regulation.
Please refer to “DRIVING METHODS OF LED MODULE”.
De-rating may be needed under low input voltages. Please refer to the “STATIC CHARACTERISTIC” sections for details.
The length of set-up time is measured at the first cold start. Turning ON/OFF the driver may lead to increase in the set-up time.
The driver is considered a component that will be operated in combination with the final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
To fulfill the requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without being permanently connected to the mains.
This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
Please refer to the warranty statement on MEAN WELL’s website at http://www.meanwell.com.
The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitudes higher than 2000m(6500ft).
For any application note and IP waterproof function installation caution, please refer to our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf
BIS certification is for HLG-320H-A only, but products sourced from Taiwan do not have the BIS logo, please contact your MEAN WELL sales for more information

DRIVING METHODS OF LED MODULE

This series is able to work in either Constant Current mode (a direct drive way) or Constant Voltage mode (usually through additional DC/DC driver) to drive the LEDs.

Typical output current normalized by rated current (%)

DIMMING OPERATION

3 in 1 dimming function (for B/AB-Type)

·Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-:
1 ~ 10VDC, or 10V PWM signal or resistance.
Direct connecting to LEDs is suggested. It is not suitable · to be used with additional drivers.
Dimming source current from power supply: 100μA (typ.)

Applying additive 1 ~ 10VDC

Applying additive resistance:

Note: In the case of turning the lighting fixture down to 0% brightness, please refer to the configuration as follows, or please contact MEAN WELL for other options
