AC-DC power supply series offer high power in compact, low-noise package
TDK Corporation announces the addition of 1200 W rated models to the TDK-Lambda CUS-M series of 30 W to 1500 W AC-DC power supplies. These latest products have a 187 x 93 mm footprint and a low 42.5 mm profile.
The CUS1200M features a variable speed fan with audible noise as low as 30 dBA at 20 % load and 42 dBA at full load. The power supplies can be used in a wide range of applications, including medical, dental, test and measurement, broadcast, and industrial equipment.
The series accepts an 85 to 265 Vac input, delivering full power at 90 Vac, and is available with 24 V, 36 V, and 48 V outputs. A 5 V 2 A standby voltage, remote on/off, remote sense and a power good signal are fitted as standard.
