Motor Controllers That Cut Peak Load Charges

Peak load charges catch a lot of businesses off guard because they're often driven by a single brief event rather than ongoing consumption. A large motor starting direct on-line can create a current spike sharp enough to register as a new demand peak, and depending on the tariff structure, that peak can influence charges applied across the whole billing period.

Integra from Suresense reduces this risk at the point it's created. Its soft start function smooths the current draw during motor start-up, avoiding the sharp spike a conventional direct on-line start produces. Because the ramp up is gradual rather than instant, the demand recorded by site metering stays considerably more level.

This matters most for sites running several large motors, particularly where multiple motors might start in close succession and compound the demand spike further. By managing that risk automatically, Integra reduces exposure to peak load charges without requiring any chang

e to operational scheduling or manual intervention around when equipment is switched on, sitting alongside the direct energy savings the controller delivers during normal running.

Sites unsure whether they're currently exposed to peak demand penalties can ask their energy supplier or Suresense to review recent billing data alongside their motor start-up patterns.
