Our L23 standard series DC power supplies are designed to drive HeNe lasers up to 15mW. Each L23 provides greater than 75% efficiency and, therefore, does not require additional heat sinking (with the exception of those drivers operating in the AE power range). See below for additional information on power ranges. Units in the AE power range provide approximately 7.5 square inches of heat sink.
L23101
The L23101 is a standard DC input power supply designed for OEM integration. The unit has an input voltage of 10-14VDC and is available in four power ranges from 2.5 to 25W.

Power Ranges For AC & DC Power Supplies
We offer AC and DC input power supplies in a variety of power ranges. The following labeling system is used to denote a particular power range.
Power ranges (DC input units)
Power ranges (AC input units)
L
low power
I
very low power
M
medium power
D
low power
H
high power
No letter
standard power
E
special high power unit with 39% more output power capability than an "H" power range unit
E
special high power unit with 39% more output power capability than a standard unit
Please note: To indicate that the high voltage return lead is at ground potential, an "A" should appear before each letter above. For example, "AH" tells us not only that the high voltage return lead is at ground, but that the power range is high. Ground can be either negative or positive.
