QuadTech Inc-Programmable DC Power Supply (Model: 62000P Series)

• Wider range of voltage & current within the power rating of the power supply
• Constant power operating envelop
• Voltage range: 0 ~ 600V
• Power range: 600W, 1200W, 2400W, 5000W
• High-speed Programming
• Precision V&I Measurements
• Current sharing for parallel operation with Master/Slave Control
• LXI option now available! See LXI compliance.

The 62000P Series DC Power Supply includes 9 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 typicalATE and benchtop applications.

Advantages include 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. 600W to 5000W constant power designs are available ranging up to 600V and 120A. GPIB, RS232 and USB control options are available as are Labview Softpanels.

Features and Benefits

This DC Power Supply includes many unique features not generally available in other commercial power supplies on the market:

• Constant power operating envelope: Provides higher currents at lower voltages. This means that one power supply can do the job of two or three conventional supplies. No longer to you need to buy both high current/low voltage and low current/high voltage supplies to test a family of converters.
• High Accuracy current readback: This means that current shunts/mux/DMMs are no longer needed to measure the converter's input current accurately which is critical to good efficiency measurements. Therefore work benches and test systems are less complex, less costly and can cover a wider range of converters.
• DC Transients: The 62000P DC Power Supply provides programmable control over voltage and current rise and falls times. This allows complex dc transients to be generated which are not possible with conventional power supplies. Supports:

  – Automotive transient testing per ISO16750-2
  – Shipboard – DO-160

• Output Trigger: The 62000P DC Power Supply provides output trigger timing and precision event capturing. Ideal for ATE systems desiring to capture oscilloscope waveforms.
• VID Control: Instruments include 8 independent programmable TTL signals which can be used for VID control or any general purpose logic controls.
• Soft Panels: Advanced Labview graphical control panels allows for simple and efficient control and data gathering for the 62000P DC Power Supply supplies.

Wide Operating Region With Constant Power

The 62000P Series DC Power Supplies offer a wide operating region. For example, the output specification for model 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.
