Pico Electronics: SERIES LR MILITARY DC-DC CONVERTERS
Page 1 of 3
SERIES LR
DC-DC CONVERTERS
Wide Input Range/up to 3.33:1
Isolated Regulated up to 5 Watt
DC-DC Converters
Fully Regulated
All Units Shielded
This series of high efficiency, wide input range, encapsulated regulators come in 90 different
FEATURES
models. These units feature a 500 VOLT DC input to output isolation in both single and dual output
models. The LR Series will operate over a temperature range of -25º C to +70º C with no heat sink
Voltage regulation over input range of
or electrical derating. These units are excellent for applications where input voltage varies
dramatically, yet a high efficiency and output voltage regulation must be maintained.
Unit
TYPICAL CHARACTERISTICS:

25º C ambient.
Operating temperature:
-25º C to +70º C ambient.
Output voltage tolerance:
±1% at typical input voltage
Output voltage temperature coefficient:
0.02%/ºC
Storage temperature:
-55º C to +125º C
Short circuit protection:

5-15V DC = ±1.5%
8-24V DC = ±1.5%
18-36V DC = ±1.0%
36-60V DC = ±1.0%
18-60V DC = ±1.5%
High efficiency - up to 80%
Will operate over a temperature range of -25º C to +70º C with no heat sink or electrical derating
6 sided shielding
Isolation - 100 megohms at 500 volts DC
External output trimming pin standard, +5%
Single and dual isolated outputs
Each unit is supplied with an external control pin. This "C" pin, when connected to the negative (-) input,
will disable the unit, allowing for remote shutdown.
