GBD560/4 Helios 3ph Gigabox - Which controller?
13/03/23
Hi. Can you recommend a controller for GBD560/4 Helios 3ph Gigabox centrigugal fan – SKU gbd560/4? Thanks
Answer
Hi. Thanks for the question. Helios’s recommended speed controller to suit the fan is either the RDS 7 (with motor protection) or the TSD 7 (without motor protection). We would always suggest using motor protection. You could also use an inverter speed controller, but unless this is approved by Helios they may not honour the warranty in the event of an issue.
