Buffering with electrolytic capacitors instead of lead acid batteries
Type buffering time of 350ms @22Vdc/20A
Buffer mode selectable by switch:
fixed mode at 22Vdc
Dynamic mode for Vin-1Vdc
LED indicator for signal status
Supports parallel connection to extend buffering time
Cooling by free aur convection
