9940 – Battery Charger, Lead Acid Batteries: 40W
- Universal input 90~264 VAC.
- 3-step charge control with timer.
- 12V, 24V and 36V standard models.
- Plug-in switch mode design.
- LED indicators with three different colours.
The 9940 series is part of a family of 3-Step chargers from 10 – 240 watts. These 3-step chargers are designed for Cyclic applications, where the need to re-charge a battery as quickly as possible is the main requirement.
The charger operates in a boost/timer mode for approximately 2 – 3 hours. At the end of the timer period, the charger will return to a Float Voltage level, where it can be left on indefinitely. The timer is automatically activated when the AC power is switched on.
