ERP Power’s VZM Series of LED drivers offer a programmable 0-10 V dimming constant voltage solution in an efficient and compact IP20-rated case.

Nominal input voltages are 120 VAC and 277 VAC, with output voltage options of 24 VDC and 48 VDC.

The drivers comply with ENERGY STAR®, DLC (DesignLight Consortium®), and CA Title 24 technical requirements.

The case dimensions are as follows:
Length: 150.2 mm (5.91 in.)
Width: 38.8 mm (1.53 in.)
Height: 24.9 mm (0.98 in.)


WHAT MAKES VZM SERIES DRIVERS SO SPECIAL?

– The small size of the drivers enables design freedom for multiple constant voltage applications

– Programmable output voltage for optimal dimming range

– Fully programmable 0–10 V dimming, for a wide range of LED loads and dimming profiles

– UL Class P, Class 2, and Class II


ACHIEVING BEST DIMMING PERFORMANCE WITH THE VZM SERIES:

1. Determine operating voltage. This will most likely be either 24 V or 48 V. A lower voltage can be used if desired for thermal performance, extended LED lifetime, etc.

2. Measure the minimum voltage at which the LED produces light to 0.1 V precision.

3. Use the programming software to set the maximum and minimum voltage of the VZM in the ”Operating Voltage” and “Minimum Dimmed Voltage” fields, respectively.

4. Choose desired dimming profile from the drop-down menu, or define a custom dimming profile.

5. Save the dimming configuration in the GUI for use in lot programming.


EXAMPLE:

48 V LED strip that produces light down to 35.1 V and will be max output at 48 V.
“Operating Voltage” will be set to 48 V, and “Minimum Dimmed Voltage” will be set to 35.1 V.
User chooses 1% w/ dim-to-off dimming profile.


NOTE: The VZM is capable of programming output voltages from 100% to 65% of max output voltage. For LEDs that remain on below this threshold, 1% dimming is not achievable. It is imperative customers test the VZM with their load to determine if 1% dimming is attainable.
