CURRENT or POWER PROFILE

According to profile stored previously in TORKEL:

Specify time and current or power for each step

Up to 19 steps in a profile

9 current and 9 power profiles can be stored

CURRENT MEASUREMENT

TORKEL measures the current and bases the regulation on: current through TORKEL current in an external circuit measured with a DC clampon ammeter

TIME-SAVING AND

CONVENIENT

Automatic regulation - you do not need to spend time and attention on adjusting the current

Alarm when voltage approaches end-of-test voltage

Higher current - shortened testing time

(also reduces recharging time)
