Apparently an industry first, the LP Series dc/dc converters feature a 4:1 input range (9V to 36V) and deliver a 240W from a 2.3" x 2.4" x 0.55" package. Output voltages available are 12, 15, 24, 28, and 48 Vdc. No minimum load is necessary for proper operation and all models are fully isolated from input to output. The case is floating and grounds via a variety of options. Other features include efficiencies as high as 90%, fixed switching frequency of 210 kHz, and an operating temperature range from -40°C to +100°C. CALEX MFG. CO. INC., Concord, CA. (800) 542-3355.
