Dynamo Regulators Ltd will be closed for business until 12th June. Sorry for lack of prior notice

May 27, 2019:

Dynamo Regulators is very pleased to announce that it has agreed to licence all aspects of manufacturing and marketing for the DVR3 & 4 regulators to a Dynamic new Company. The aim is to complete the transfer during July. Unfortunately, due to changed circumstances DRL is unable to accept further orders for the DVR3 & 4 products with immediate effect. Please note that DVR2 availability is not affected by these changes. We are sorry for any inconvenience during the transfer period. Further details will be posted here when these are available.

Heatsink (for DVR3™ & DVR4™)



Our DVR3 and DVR4 regulators are designed to be attached to a flat metal surface via the supplied bonding pad to provide a path to conduct heat away from the electronics (ideally a flat bulkhead away from direct engine heat). If this is not feasible this strongly self adhesive heat-sink affixed to the regulator will limit its temperature rise when placed in a cooling air stream. The low heat output from versions up to 22 Amps * means that the extra heatsink is not of practical benefit. The 22 Amp regulator will run significantly cooler, and the heatsink will reduce case electronics temperature in an installation where heat is unable to be conducted away.

It is worth noting that the heatsink will give only a limited cooling effect if surrounded by the original control box casing, so that air movement is restricted. In reality the heatsink is actually a device to facilitate heat transfer. It does not somehow swallow up the heat from the regulator. It simply increases the surface area contacted by the air. If the air is not free to convect away the result is hotter air and a hot regulator casing.

The size of the heatsink is 40 x 40 x 18 mm.

* all types have lower heat output from mid 2016.

Only available when purchasing a Regulator.
