General Information
Model PST-3P10-N0504B
Name 2.4 Volt charger for NiMH and NiCad Batteries.
Type Battery for R/C, Robots, instruments, toys
ROHS ROHS available on special order
Technical Information
Rated input voltage 90-264 VAC, 50/60 Hz, 0.1 Amp input typical
Battery Voltage 2.4VDC packs
Input Frequency 50-60 Hz
Cell count (series) 2 cells for 2.4V
Charging current 700 mA typical, 1 amp peak
Battery size 100mAH to 5600 mAH
Charger type Nickel Metal Hydride or Nickel Cadmium chemistry
Charging algorithm   Constant current -Delta V
Termination -0.5mV per cell, 1.6 V per cell or 8 hour time out
Green "Charged" light turns on and trickle charge turned on at Termination
Important note: Due to the erratic charge behavior of NiMH and NiCad batteries when first placed on charge there is a delay of up to 15 minutes before an accurate charge termination can be read. In worst case a battery can be taken off the charger and reattached, and charged for 15 minutes before the "charged" light comes on again. In addition, new packs should be charged and discharged several times before they "settle in" to a predictable charging condition.
Output power 4W maximum
