Chroma’s new 62000P Series of programmable DC power supplies offer many unique advantages for ATE integration and testing. These advantage include a constant power operating envelope, precision readback of output current and voltage, output trigger signals as well as the ability to create complex DC transients waveforms to test device behavior to spikes, drops, and other voltage deviations. Designed for automated testing DC-DC converters and similar products, the 62000P sets a new standard for high accuracy programmable DC supplies.

The 62000P Series includes 12 different models ranging from 600W to 5000W, up to 120A and up to 600V. Due to their constant power operating envelope a single instrument can provide both high voltage/low current AND low voltage/high current thereby reducing the number of supplies needed in typical ATE applications. The 62000P Series also includes 16 bit readback capability for accurate voltage and current readings. This means systems no longer need complex shunt/multiplexers to make accurate readings of the UUT’s input parameters. The instruments also include I/O ports providing 8 bit TTLs, DC-ON, fault output signal and remote inhibit as well as a output trigger signal for system timing measurements.

Another unique capability of the 62000P Series supplies is their ability to create complex DC transient waveforms. This capability allows devices to be tested to DC voltage dropouts, spikes and other voltage variations making them an ideal choice for airborne device testing, inverter testing and other devices which will experience voltage interrupts. Applications include DC/DC Converter & Inverter voltage drop test, engine start-up simulation, battery automated charging, electronic product life cycle test, and etc.

Differentiators

• Constant Power Envelope means one of our power supplies usually can replace 2 or 3 of other brands
• Ability to generate transient waveforms for testing to industry standards for airborne, shipboard, automobile, etc
• High accuracy readback means efficiency readings can be made directly from DC source instead of using external shunts and DMMs
• Output trigger signals allow scopes and other devices to be triggered for timing measurements
• Available softpanels

Wide Operating Region With Constant Power

The 62000P Programmable DC Power Supplies offer a wide operating region. For example, the output specification for the 62012P-80-60 is 1200W/80V/60A, it allows operating flexibly in various combinations as shown in the figure to the right. Conventional power supplies provide the same rated current at all output voltages, however, the 62000P DC Power Supply provides greater current at lower output voltages. This means both low voltage/high current and high voltage/low current UUTs can be tested using a single supply avoiding the need for multiple supplies.

Master/Slave Parallel & Serial Control

When high power is required, it is common to connect two or more power supplies in parallel or series. The 62000P Series DC Power Supplies have a smart Master/Slave control mode making series/parallel operation fast and simple. In this mode the master scales values and downloads data to slave units so programming is simple and current sharing is automatic.

Programming Sequences Applications

The 62000P series DC Power Supply allows for 100 user programmable sequences with time settings ranging from 5ms to 15000s, voltage/current slew rate control and 8 bit TTL output for automated test applications. Applications include DC/DC Converter & Inverter voltage dropout testing, engine start-up simulation, battery automated charging, product life cycle testing and airborne avionics testing.
