For heatsink option, add suffix “H” to model number (i.e. B5003RW-H)
Derating Curve
Notes:
ꢀ. Load regulation is specified for a load change of minimum load to full load.
2. When measuring output ripple, it is recommended that external ꢀ.0 µF & ꢀ0 µF capacitors be placed in parallel
from the +Vout pin to the -Vout pin.
3. Transient recovery is measured to within a ꢀ% error band for a load step change of 75% to ꢀ00%.
4. The maximum control current at the on/off pin (pin 6) during a logic high is 5 µA. The maximum control current to
the on/off pin at logic low is -ꢀ00 µA. If the on/off pin is left open, the unit operates. If grounded, the unit will shut off.
5. The B5000RW series can meet EN55022 Class A with the addition of a capacitor connected in parralel with
the input pins. It is recommended that a low ESR (ESR <ꢀ.0 at ꢀ00 kHz) capacitor be mounted close to the
converter. For ꢀ2V input units, a 22.0 µF/25V is recommended; for 24V inputs a 3.3 µF/50V; and for 48V units a
2.2 µF/ꢀ00V.
6. The converter should be connected to a low ac-impedance source.An input source with a highly inductive imped-
ance may affect the stability of the converter. In applications where the converter output loading is high and input
power is supplied over long lines, it may be necessary to use a capacitor on the input to insure start-up.
7. Operation at no-load will not damage these units. However, they may not meet all specifications.
8. An external resistor may be used to adjust the converter output by ꢀ0%.To adjust the output UP, connect a 5%,
3W resistor between the minus output pin and the Vout trim pin. To adjust the output DOWN, connect a 5%, 3W
resistor between the plus output pin and the V trim pin. For continuous UP/Down trimming capability, connect
a ꢀ0 kW potentiometer between the plus andOmUT inus outputs with the wiper arm connected to the VOUT trim pin.
The trim pin may be left floating if it is not used. Contact the factroy for more information.
9. It is recommended that a fuse be used on the input of a power supply for protection. See the table above for the
correct rating.
