• Manufacturer: BTCPOWER [Broadband TelCom Power, Inc.]

Prelim. Specification
S15-48-15D
Basic Operation And Functions
S15-48-15D is a high efficiency, isolated DC/DC
converter. Neither heat sink nor airflow is
required when the unit operates at ambient
temperature of 25 C. The unit has basic control,
output adjustment and protection functions.
Input (Pin 2, Pin 3)
Input power Vin(+) must be connected to Positive
input pin 3; Input power Vin(-) must be connected
to Negative input pin2.
Output (Pin 4, Pin 6)
Output power Vout(+) must be connected to
Positive output pin 4; Output power Vout(-) must
be connected to Negative output pin6.
Output Common ( Pin 5)
Pin 5 is Vout(+) and Vout(-) common pin.
ON/OFF (Pin 1)
Permits the user to maintain unit On/Off, in order
to properly sequence different power supplies
and reduce power consumption during the
standby condition. On/Off pin(pin 1) is referenced
to Vin-.
Pin 1 is the "Enable" pin, connecting a TTL
compatible pin. A TTL control signal to this pin,
according to the specification, turns the unit on or
off.
The positive logic unit turns on when the pin is at
logic high or open, and turns off at logic low.
The negative logic unit turns on when the pin is at
logic low, and turns off at logic high state.
Typical ON/OFF connection is shown in Fig 1.
