TDK Corporation announces the introduction of two
additional DRB DIN rail mount AC-DC power supplies, rated at 120W and 240W (144W/288W
peak for 10 seconds). The products have
a very narrow width, providing additional space for other DIN rail mount
modules. Having efficiencies of 93%,
less internal heat is generated resulting in cooler electrolytic capacitors a
field life of greater than 7 years at 75% load, 230Vac input. These models complete the cost effective 15W
to 480W DRB series, making it suitable for a wide range of industrial applications
including factory automation, process control and test and measurement.
The DRB120 and DRB240 models are housed in a robust
metal enclosure, measuring 124mm in height, 125mm deep and widths of 35mm and
41mm respectively. The power supplies
can operate from a wide range 85 – 264Vac input and withstand a surge of 300Vac
for 5 seconds. Both have a 24V output
and feature an isolated DC OK opto-coupler signal in addition to an LED
indicator. The outputs can be adjusted
from 24 - 28V to compensate for series blocking diodes or FETs in redundant
configurations.
Input to output isolation is 3,000Vac, input to ground
1500Vac and the output to ground is 500Vac.
The DRBs are convection cooled and rated for operation in -25 to +70oC
ambient temperatures (cold start at -40 oC), derating linearly above
55 oC to 50% load at 70oC.
The units are safety certified to IEC/EN/UL/CSA
60950-1, IEC/EN/UL 62368-1, UL 508, IEC/EN 62477-1 (OVC III), and are CE marked
for the Low Voltage, EMC and RoHS2 Directives.
Both meet EN55011-B, EN55032-B, CISPR11-B, CISPR22-B, EN61204-3 (Class A)
radiated and conducted emissions, and comply with the EN61000-4 immunity
standards.
