Log into view price

 

The 257CH-9 Saft nickel-cadmium battery consists of a box (020), containing 20 individual cells CVH250KA. These cells are connected in series to obtain 24 V nominal. Individual cells are enclosed in a polyamide container that provides insulation, allowing them to be fitted side-by-side in the battery box. Interconnection of cells is via rigid, highly conductive, nickel-plated copper links (180 to 240). Each link is held in place by nickel-plated copper nuts (130) on the cells’ terminals. Inside the battery box, individual cells are held in place by partitions, liners and spacers (040), and a cover (030). The terminals (050) connects the battery to the aircraft DC power. The cover (030), which can be removed, is attached to the box (020) by 4 latches.

Benefits

  • The battery is charged on the aircraft by an on-board charger.
  • The charge control thermistor provides a signal to the charger to compensate the charge according to the battery temperature.
  • The thermostat will cut off the charger if the battery temperature exceeds a safe operating limit.
  • The battery plates store electrical power supplied by a charging source, and supply power when the battery is connected to a load circuit, i.e. when it discharges.

Aircraft Applicability

  • Candair( Bombardier) : BD7 00 1A10, BD 700 1A11, BD 700 1A12
  • Bombardier : Global Express GL511-2201-1, BX00101-01, BA34-01
