Q-SET+QZ LED Power Supply 30W-96W

Product Overview

The Q-SET+QZ is Q-Tran's direct burial and outdoor-rated electronic power supply, designed for installation in the Q-VAULT-5 enclosure. It functions as a versatile Class 2 LED driver, available with dimming or non-dimming capabilities. For dimming applications, it supports control via forward or reverse phase or 0-10V. A dimmer with a neutral connection is recommended for optimal performance with phase control dimming. The Q-SET+QZ operates on a universal input voltage of 110-277V and provides a 24VDC secondary voltage. It is offered in 30W, 60W, and 96W capacities and is fully listed for direct burial use when installed within the Q-VAULT enclosure.

Part Number Builder

The part number is built around the product code "Q-SET+QZ". Specific configurations are determined by size (30W, 60W, 96W), primary voltage (UNV), secondary voltage (24VDC), control options (ND for Non-Dimming, PH/010 for Phase/0-10V dimming), and other options (N/A PS, PS for Pool & Spa).

Voltage Drop Chart

This chart illustrates the maximum distance (in feet) from the power supply for a 5% voltage drop, based on wire gauge and load wattage at 24VDC.

Wiring from the power supply to the light fixture must use two-conductor cable. Distances are based on a 5% voltage drop maximum. Installation must comply with all applicable codes and be performed by a qualified individual.

Product Dimensions and Design

The power supply unit has dimensions of 10.70"L x 9.78"W x 2.34"D. It is designed to fit within the Q-VAULT-5 enclosure, which is IP68 rated and suitable for direct burial in soil, gravel, and concrete. The Q-VAULT-5 enclosure can accommodate up to one Q-SET+QZ unit.

Performance Curves

Derating Curve

[Diagram Description: A line graph titled "Derating Curve" shows the relationship between Load (%) on the Y-axis and Ambient Temperature (°F) on the X-axis. The curve starts at 100% load at lower temperatures, gradually decreases, and reaches 0% load around 140°F, indicating the power supply's derating behavior at elevated temperatures.]

Dimming Curves

[Diagram Description: Two graphs illustrate dimming performance. The "PH-010 QZ Dimming Curve" shows Dimming Percentage (%) on the Y-axis against 0-10V Voltage [V] on the X-axis, depicting a linear relationship. The "QZ Dimming Curve" also shows Dimming Percentage (%) on the Y-axis against 0-10V Voltage [V] on the X-axis, but with a different, non-linear curve.]

Wiring Diagrams

The following diagrams illustrate the input and output connections for different operating modes.

Phase Dimming (30W, 60W, 96W)

[Diagram Description: A wiring diagram shows input terminals labeled HOT, NEU, GND, and output terminals labeled '+', '-'. The input side connects to a "Phase Dimmer". The output connects to LED fixtures, with specific wires for 30W, 60W, and 96W loads. A note indicates "This wire can be pink or grey".]

0-10V Dimming (30W, 60W, 96W)
