Terminator Cable — Systemair EC Fan Full-Power Bypass

Terminator Cable — Systemair EC Fan Full-Power Bypass

A terminator cable that plugs into the EC socket of a Systemair EC fan and forces the fan to run at 100% power continuously — bypassing any external controller. Useful when you want maximum output without a controller in the loop, or as a diagnostic tool when testing whether a controller is the fault.

Why growers need a terminator:

• Forces 100% fan speed — no controller required, fan runs flat-out
• Diagnostic use — rules out the controller as a fault source when a fan isn't behaving correctly
• Emergency backup — if your controller fails mid-grow, this keeps the fan running at full until you can replace it
• Compatible with Systemair EC fans — confirms fan is hardware-OK by isolating it from control signals

Who it's not for:

Only works with Systemair EC fans — not compatible with other EC fan brands or AC fans. If you want variable speed control, you need an EC-compatible controller; this cable is specifically for full-power operation only.
