Telos 320W Growcast Driver Identification Guide

Telos 320W Growcast drivers are available in three configurations, each designed for specific generations of Telos grow lights.

Although these drivers share the same power rating and Growcast control technology, their electrical connectors differ depending on the fixture model.

This guide explains how to identify your Telos Dynamic 930 version and select the correct replacement driver to ensure compatibility and reliable operation.

How to Identify Your Telos Dynamic 930 Version

The simplest way to identify your Dynamic 930 version is by checking the product label located on the heatsink.

There are two versions of the Dynamic 930, each requiring a different Growcast driver.

Dynamic 930 V1

The original Telos Dynamic 930 can be identified by its product label, which displays a weight of 4.43 kg.

The label is located at one end of the heatsink and is the only label fitted to the fixture.

Key Identification Features:

• Product label displays a weight of 4.43 kg.
• A single product label is located at the end of the heatsink.
• No additional warning label is fitted.

Dynamic 930 V2

The updated Telos Dynamic 930 features a revised product label with additional technical information.

The label extends across the full width of the heatsink and displays a weight of 4.55 kg.

Unlike V1, the V2 fixture also includes a separate warning label in English and French, positioned at the opposite end of the heatsink.

Key Identification Features:

• Product label displays a weight of 4.55 kg.
• A full-width label contains additional technical specifications.
• A separate English and French warning label is located at the opposite end of the heatsink.

Identifying the Correct 320W Growcast Driver

Telos uses three versions of the 320W Growcast driver, each featuring a different connector configuration.

All three are built around a 320W Inventronics driver with integrated Growcast technology.

The input and output connectors provide the most reliable way to distinguish between the different driver versions.

Driver Compatibility Overview

Choosing the Correct Replacement Driver

Before selecting a replacement driver, confirm your fixture version and check the existing connector configuration.

For Dynamic 930 fixtures, use the product label to identify whether you have V1 or V2.

Although all three drivers operate at 320W, their different connector configurations mean they are not directly interchangeable.

Only use Telos-approved replacement drivers. Always disconnect the fixture from mains power and allow it to cool before handling any electrical connections.
