62000E Series Programmable DC Power Supply 1U

Chroma 62000E Series of Programmable DC Power Supplies provide single-channel output of 1.7kW, 3.4kW, and 5kW, as well as threechannel of 1.7kW output each configured in an industry-leading high power density 1U chassis. The 28 models offer fixed- and autorange output with current ratings up to 22.5A and voltage ratings up to 1200V.

The 62000E series provides constant voltage (CV) and constant current (CC) modes so that users may switch the output priority based on testing requirements. Along with its high precision measurement output, its high-speed transient response and low noise satisfies a variety of devices and test applications in both labs and automated test system integration.

These power supplies serve both single and multi-channel test applications, such as D2D power system ATEs, automotive component systems, reliability of aerospace satellite power systems, long-term durability of active and passive components, industrial and medical system integrated power supplies, supply and aging of semiconductor power components, LED and laser diode, production and aging of solar modules, etc.

Compared with traditional power supplies, the Chroma 62000E series saves room by expanding usable rack space, decreases energy consumption, and simplifies testing at a competitive price.

The 62000E series DC power supply has 100 programmable sequence settings. Through List Mode, users can customize the desired output waveforms and set the dwell time between 10ms and 65535s to meet various test requirements. These functions apply to voltage drop testing of DC/DC converters and inverters, life cycle testing of components, aviation testing of aircraft, etc.

The 62000E series DC power supply has 1-phase/3-phase 200~240Vac and 3-phase 380~400Vac input with active PFC and 92% high efficiency. This helps customers to save electricity costs and power capacity distribution when performing high power testing, and adapt to a range of power systems around the world. In addition, the power supply can be controlled by the supported digital USB/LAN(LXI)/CAN FD/GPIB and analog APG interfaces based on integration requirements of the DUT system.

High Power Density 1.7kW x 3CH in 1U

The industry-leading high power density design enables 3 channels of 1.7kW output in a 1U chassis. Each channel is isolated for independent voltage/current control and measurement that saves cabinet space for system integration and simplifies cable configuration. For example, take a system integration manufacturer who requires nine channels of programmable DC power. Other 1U supplies would require 9 single-channel power supplies stacked at a height of 9U, while the 62000E series power supply can do the job with only 3 units at 3U height (using 3-channel models).

The 62000E series has auto-range output and fixed-range output power supply options available for selection based on the customer’s application, specification, and budget. For example, the 62050E-600P is an auto-range model with output specifications of 5kW/600V/22.5A that can be flexibly operated in different combinations (as shown in the figure on the left). It provides a 22.5A large current when outputting 223V low voltage and a small current of 8.4A at 600V high voltage. This means a customer with DUTs that need to be tested by both low voltage/high current and high voltage/low current can choose an auto-range DC power supply. The 62050E-600P can be used in an ATE for test & measurement to replace multiple DC power supplies, saving cost and space.

The 62050E-600 model is an economical fixed-range power supply designed with an output of 5kW/600V/8.4A DC source (as shown on the right). This fixed-range supply can provide power for manufacturing, giving the equipment supplier a cost-effective power source for integration when producing DUTs with fixed specifications.

Users must consider compact size, light weight, high utilization, flexibility of assembling/disassembling multiple power systems, as well as system failure maintenance time, since each of these factors will affect the R&D and production line. The 62000E series DC power supply has a master/slave control mode to parallel up to 4 devices with a maximum of 20kW. The easy-to-operate parallel operation mode is convenient for R&D labs, verification units, and production lines to use. In this mode, the master will download the setting values to the slave units allowing users to operate it like a standalone unit. The parallel system adopts a digital current sharing design with high stability and anti-noise interference.

* Requires optional A620042 interface.
* Call for availability.

The 62000E series DC power supply has built-in List and Step modes for users to program the sequence and timing. The software provides 100 steps of dwell time ranging from 10ms to 65535s, voltage and current control, as well as I/O signal output for automated testing. These functions are applicable for voltage drop testing of DC converters and inverters, auto battery charging, life cycle testing of components, aircraft aviation testing, etc.

The 62000E series DC power supply contains a state-of-the-art user control interface. The intuitive touch panel and user-friendly interface aid easy operation, similar to using a smartphone. Through the icons on the touch panel, users can conveniently complete all voltage/current settings and measurements, program sequence control settings, etc.

The 62000E series displays a standard LAN interface compliant with the Ethernet/LXI standards. The remote web control interface provides remote operation functions, allowing users to enter their account and control the power supply via smartphone, tablet, and PC monitoring equipment. This increases convenience for long-term product aging life cycle testing and DC power supply status monitoring of the DUT anytime and anywhere (patent no.: CN111796982A).

* The 62000E series provides Foldback functionality, which allows the equipment to set the output state as continuous or off when the output mode is switched (CV to CC or CC to CV). A delay off time can be set to protect the DUT. * When the power supply is abnormal, besides a warning message on the control panel, the remote control interface will also give a voice alarm. * Through SCPI command programming, users can perform program control (e.g. loop/pause/delay) and save/reload the control program to the computer. * The web software is for monitoring only and offers password-protected control authority for safe remote control. * The web software enables log in through a QR code for quick connection and control.

The 62000E series DC power supply is equipped with a VNC server. Users can readily operate and monitor remote instruments through mobile devices such as smartphones and tablets via the VNC client viewer, which also offers password-protected management of user functions and permissions.

SCENARIO 1 When the 62000E Series DC power supply is integrated into an ATE, users can perform sequence control through the GPIB interface. This eliminates the need to visit the laboratory for checking the readings and status on the device panel. The VNC function allows remote reading of the power supply output and operating status easily through the LAN interface.
	SCENARIO 2 When the power supply is used for long-term burn-in and aging tests on the DUT, the engineer can quickly connect to the power supply at any time. For example, view the test status of the device in the laboratory remotely from the office and greatly save on inspection time and effort.
SCENARIO 3 When the power supply is placed on a test bench, desk, or rack (depending on the space available), having to manually operate the power supply and on-line adjust or monitor the output would be inconvenient for the engineer. Through the VNC function, a mobile device can act as a remote control keypad which greatly benefits such tasks. To keep safe, the remote control authority is protected with a password.
