Product Benefits
- Energy savings without sacrifice—smooth dimming down to 10% lowers wattage while maintaining comfortable, consistent light output.
- Flexible control options—works on the EcoSystem digital link for networked control, or via 3-wire wallbox dimmers for local control.
- Integrated sensor support—connect occupancy and daylight sensors directly to the ballast for code-friendly, space-level control.
- Quiet, reliable operation—programmed rapid-start design, end-of-lamp-life protection, and ultra-quiet Class A sound rating.
Key Features
- Five control inputs: EcoSystem link, 3-wire, daylight sensor, occupancy sensor, and personal control (IR/wallstation).
- Non-volatile memory restores settings after power loss; factory 100% tested for performance.
- Low harmonics across the dimming range with THD <10% and power factor ≥0.95.
- Protected against miswires on inputs and lamp leads for safer installation.
- BAA-compliant models available (order with “U” prefix, when applicable).

Application Examples
- Open offices & classrooms—pair with occupancy and daylight sensors for automatic savings.
- Conference rooms—EcoSystem scenes via wallstations or IR for presentations.
- Corridors & break areas—3-wire local dimming with future-ready digital link.
- Retrofits—drop-in T8 ballast replacement where networked control is planned.
Installation Tips
- Do not switch the line/hot feeding the ballast if using EcoSystem link—keep line unswitched for full system functionality.
- Lead lengths: keep ballast-to-lamp socket wiring ≤7 ft for T8; Class 2 sensor runs up to 50 ft using 22 AWG solid.
- Separate Class 1 and Class 2 wiring; where not possible, use 600 V insulated cable with shield bonded to ground.
- Mounting clearance: maintain proper lamp-to-grounded metal spacing to avoid flicker and extend lamp life.
- Verify polarity-insensitive E1/E2 wiring; use consistent wire colors across fixtures to reduce errors.
FAQ
Does this ballast require the EcoSystem digital link to operate?
No. It can operate stand-alone with 3-wire phase control or as part of a network on the EcoSystem digital link.
What lamps are supported?
Two F32T8 linear fluorescent lamps. Other EC5 models support different lamp types; this model is optimized for T8.
How low can it dim?
Continuous dimming down to 10% relative light output.
Can I connect sensors directly?
Yes. One occupancy sensor, one daylight sensor, and one IR/wallstation input are supported via Class 2 terminals.
Is the EcoSystem link polarity sensitive?
No. E1 and E2 are polarity-insensitive and support various topologies.
What’s the maximum wiring distance on the EcoSystem link?
Depends on wire gauge; for example, 18 AWG supports up to 550 ft and 12 AWG up to 2200 ft on a single link.
Is it suitable for emergency lighting?
Not when controlled by a 3-wire wallbox dimmer unless an external emergency ballast is used or the circuit is from a dedicated emergency dimming panel.
Will settings be lost after a power outage?
No. The ballast uses non-volatile memory to restore previous settings.
What is the maximum case temperature?
167 °F (75 °C). Do not exceed this at any point on the case.
Is there audible noise during dimming?
No. The ballast is rated Class A for ultra-quiet operation.
