452215-N,35W NiMH/NiCD Chargers
The Nickel metal hydride / nickel cadmium smart chargers are designed to charge packs made of either rechargeable chemistry. Each model is capable of charging various quantities of cells. Chargers are based on a nominal, universal input of 90-264VAC/50-60Hz.
Features
- Multiple charge detection options -dV (typical), dT/dt, 0dV
- Safety timer termination
- Fast charging cycle
- Charges NiMH or NiCd battery packs
- 5 versions for 3-20 cell packs
- Integral start timer to prevent initial, false -dV detection
- Reverse polarity/short circuit protection
- LED status indicator

Functionality:
Charging begins when a battery pack is connected to the charger. The LED will be orange before the fast charge starts and the LED changes to red. When the cells are fully charged and the voltage drops (because of the -dV signal from the cells), the charger will go into a top-off charge mode before switching to trickle charge mode.
During the top-off charge session, the LED will be green with short, intermittent orange flashes. When the top-off charge is complete, the charger will go into trickle charge mode, changing the LED color to green. The charge current is now reduced to a safe level, permitting the charger to stay connected to a NiCd battery pack without damaging the cells. Depending upon the specific manufacturer of NiMH cells, trickle charging in excess of 24 hours may not be permitted.
If the safety timer disconnects before -dV, the top-off charge will not be engaged. The charger will then go directly to trickle charge mode and the LED will be green in color. If the battery voltage is far below normal, the charger will stop the fast charge current and switch to trickle charge mode. The LED will then indicate "error" by flickering green and red.
If the mains are turned off, the charger will reset and start a new charge cycle if the mains are turned on again.
