Our L88 and L92 are highly efficient switching mode AC power supplies designed for a wide range of input voltages. Both are fully encased for protection from dust and moisture.
L88
The L88 can drive some of the largest HeNe tubes on the market. This AC input power supply is available in an output power range that extends from 35 to 75W, and it operates from 115 to 230VAC ± 10%. *Note: Must meet minimum order requirements.

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.
