Stabilization step up power supply unit
BD-STV


Outline
  • When operating various apparatus by the dry cell, voltage falls gradually with use time. Therefore, it is a power supply unit for keeping constant the voltage supplied to apparatus.
  • Battery voltage operates to stability below at the half of nominal value. (in the case of 2 use of a battery)
  • If it falls to the voltage of a limit before setting battery voltage to 0, a circuit will be separated automatically and the liquid leak of a dry cell will be prevented.
  • It is 6x11x4mm in micro size.
  • The voltage to 5V can be taken out by one dry cell or 2. (80 - 90% of efficiency) .
  • A standard article is output voltage 3.2V.
  • It is the internal unit of a remote control transmitter (KRT-400T), a remote control receiver (KRT-400R), and the discovery device(KRS-300S) for pursuit etc.
Directions
  • It is completion only by connecting an input and an output.
  • It is careful of an input, an output, + and - to prevent mistakes.
  • Output voltage can be changed if you specify. (Input voltage can be impressed to setting output voltage)
