DAA/DAB/DAC 500 Series

Product Overview

POWERBOX Defense Line 500 Series 

Up to 500W Single Output DC/DC Converter 

Description   The DAA/DAB/DAC, very compact DC/DC converter in chassis mount format, incorporates input filtering, input and output protections, very robust mechanical mounting and connection, optional conformal coating, required in most of the severe environment for industrial, railways, defense type of applications. The converter provides high reliability, high efficiency, input-to-output isolation, soft start, overtemperature protection, input over/undervoltage lockout. The converters wide range of inputs are protected against surges and transients and EMI filtered. The outputs are countinuously shortcircuit proof. The 100°C baseplate operation allows operation in high temperature environment. The output can be configured in many different output voltages from 3V3 to 48VDC, can be put in series and parallel, others possibilities are even possible as semi-standard versions. Wide range of accessories like input & output Bus bars, N+1 oring diodes, parallel cables are available to simplify multi units assemblies. Military options (M) make it suitable for MIL STD compliance
