Lumastream Canada Releases Thea Series LED Drivers

thea-56-watt-led-driver-pic.png Waterloo, ON (January 28, 2013) LumaStream announces the introduction of two Power Vector LED Power Supplies:

THEA 56: 56W constant current driver for powering and dimming high power LED arrays in the range of 1400mA to 2100mA. With its output voltage range from 10 to 28Vdc it is a good match for the 8x8 Bridgelux RS LED arrays or similar LED arrays.

THEA 90: 90W constant current driver for powering and dimming high power LED arrays in the range of 2100mA to 2800mA.

The 2800mA model with an output voltage range from 25 to 31Vdc is a good match for the 10x10 Bridgelux RS LED arrays or similar LED arrays.

The 2100mA model with an output voltage range from 27 to 42.8Vdc is a good match for the new Bridgelux VERO LED arrays or similar LED arrays.

Both products feature an Auxiliary 12V voltage source for active cooling and include a NTC feature (THEA 56 only) that allows thermal feedback from a thermistor for active temperature control of the LED module. THEA 56 is also available with a 5V Auxiliary output upon request.

THEA 56 and THEA 90 also incorporate the following features:

- Wide rated input voltage range of 120 to 277 Vac

- Safety Low Voltage SELV, LPS, Class 2 Output

- Efficiency greater than 87%

- Smooth dimming utilizing proprietary current pulsing methodology

- Remote mounting up to 10 ft. (3 meters) for THEA 56 and 5 ft. (1.5

meters) for THEA 90

- Over voltage, over current and short circuit protection

- LED power supply data sheets are available at or Please contact us for the THEA 90 preliminary datasheet

- UL and CE approval completed for THEA 56, pending for THEA 90

- IP50 damp/dry location rated

- 0-10V Analog Control interface and incorporate a microprocessor that

enables exceptionally smooth dimming down to 1%.

THEA 56 has UL and CE approvals completed and is in serial production.

THEA 90 engineering samples for development are available now.
