2000 WATT
AC/DC POWER SUPPLY
TXD2000
DESCRIPTION
The TXD2000 Series is a flexible, modular, 2000 Watt
design offering two high current outputs in a 5 x 8 x 12
package. Output voltages from 2.5 VDC through 48
VDC are standard. With Power Factor Correction, EMI
compliance to FCC and CISPR22, CE Mark and
immunity to EN61000-4, the TXD2000 Series is ready
for global deployment. Standard features include
Remote Sense Compensation, Output Voltage
Adjustment, Active Current Sharing, Remote Inhibit,
Power Fail Warning, DC OK Signal and Thermal
Shutdown. An optional ORing diode is offered on
models with an output voltage of 12 VDC or above.
