Chroma's new 62000P Series of programmable DC power supplies offer significant advantages for ATE integration and testing. These include a constant power operating envelope, precision readback of output current and voltage, output trigger signals, and the ability to create complex DC transient waveforms for testing device behavior during spikes, drops, and other voltage deviations. Designed specifically for automated testing of 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, with outputs up to 120A and 600V. The constant power operating envelope allows a single instrument to provide both high voltage/low current AND low voltage/high current, reducing the number of supplies needed in typical ATE applications. The series also features 16-bit readback capability for accurate voltage and current measurements, eliminating the need for complex shunt/multiplexers to measure UUT input parameters. Additional I/O ports provide 8-bit TTLs, DC-ON, fault output signal, remote inhibit, and output trigger signals for system timing measurements.

A unique capability of the 62000P Series is the ability to create complex DC transient waveforms. This allows testing of devices for DC voltage dropouts, spikes, and other voltage variations, making them ideal for airborne device testing, inverter testing, and other applications where voltage interrupts occur. Applications include DC/DC Converter & Inverter voltage drop testing, engine start-up simulation, battery automated charging, electronic product life cycle testing, and more.

• Constant Power Envelope means one of our power supplies can typically replace 2 or 3 units from other brands
• Ability to generate transient waveforms for testing to industry standards for airborne, shipboard, automobile applications
• High accuracy readback enables efficiency measurements directly from the DC source without external shunts and DMMs
• Output trigger signals allow synchronization with other devices for timing measurements
• Available softpanels for enhanced user interface

The 62000P Programmable DC Power Supplies offer a wide operating region. For example, the 62012P-80-60 model with 1200W/80V/60A specification allows flexible operation in various combinations. Unlike conventional power supplies that provide the same rated current at all output voltages, the 62000P DC Power Supply delivers 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, eliminating the need for multiple units.

When higher power is required, multiple power supplies can be connected in parallel or series. The 62000P Series DC Power Supplies feature a smart Master/Slave control mode that simplifies series/parallel operation. In this mode, the master unit scales values and downloads data to slave units, making programming straightforward while ensuring automatic current sharing.

The 62000P series DC Power Supply supports 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.
