AV1761 Programmable module power supplyDetailed product description：

The AV1761 programmable module power supply is an ideal device for providing power excitation and testing in automatic testing platforms, suitable for design and development, production and manufacturing, and other automatic testing fields. This product provides users with maximum flexibility in selecting power supplies. According to their needs, they can choose 8 types (or customize) of modules to build a power system with 1 to 8 channels, with a total output power of up to 1600W. AV1761 adopts advanced switching power supply technology to achieve high power density output, and its precise design ensures low noise output, making it an ideal power voltage source and current source.
Main features:
High power density host (0-1600W), 8 standard modules for easy selection: single module output 150W (or 200W), purchasing multiple modules can form a multi-channel output power system, a single host can be equipped with up to 8 modules (200W × 8=1600W), special requirements can be customized
Programmable fixed voltage (or current) output, and can also set voltage and current output sequences (i.e. programmable multiple sets of voltage and current that vary with time or events)
Modules can be rearranged in series or parallel to expand the output voltage and current range
Excellent performance indicators: high-precision programming and read back measurement, output pure and low-noise
Multiple set storage
Complete protection functions: overvoltage, overcurrent, and over temperature protection
Isolation and polarity reversal function (optional)
Unique connector components simplify system integration
GPIB (IEEE 488.2) interface control, optional AV86402 keyboard controller (optional) to simplify operation

Typical applications:
In the testing of PC motherboards, it is very important to use multiple ATX power supplies to power the components of the PC motherboard with the correct sequence voltage. Incorrect sequences can not only cause the components to fail to start, but also damage the tested components due to induced current locking. Therefore, a 7-channel power system can be established using the AV1761 programmable module power supply, and its output sequence and voltage can be changed through programming to verify the performance of the PC motherboard.

Ordering information:
Host: AV1761 Programmable Module Power Host
Explanation: The host is a necessary platform for the normal operation of the power module, and one host can be configured with 1 to 8 modules.
Standard configuration: DC1761XX power module (quantity: 1-8), output connector (quantity: 1-8), user manual
Instructions:
1) The module must be inserted into the host to work! All modules have the same external structure and can be inserted into any of the 8 channels of the host.
Users can prioritize purchasing 150W series standard modules (DC176101, DC176102, DC176103, DC176104, DC176105, DC176106, DC176107) according to their needs; You can also order 200W series expansion modules (DC176101A, DC176102A, DC176103A, DC176104A, DC176105A, DC176106A, DC176107A).
In addition, users can use modules in series or parallel as needed. Series connection is used to expand the output voltage, such as two 20V modules (model DC176102) with a series voltage of up to 40V; parallel connection is used to expand the output current, such as two 20V modules (model DC176102) with a parallel output current of up to 15A.
If the above modules (or combination modules formed by series and parallel connection) still cannot meet your engineering application, you can also customize a special module DC1761T according to your actual needs, including output voltage/output current range, etc. Please note that the maximum output power of the customized module cannot exceed 200W, the maximum output voltage cannot exceed 320V, and the maximum output current cannot exceed 16A!
2) The output connector is universal for all modules.
This component simplifies the assembly and maintenance of the system. Once the connecting wires are connected to the load, the connector design allows you to unplug the module from the front of the host for replacement or maintenance, eliminating the hassle of dismantling cables or removing the host from the rack.
Options: Keyboard Controller AV86402, Output Isolation and Polarity Flip
Instructions:
(1) AV86402 Keyboard Controller: This option provides full control over all programmable functions, enabling input and display of programmable parameters. When forming an automatic testing system, the keyboard can be omitted and programmed commands can be directly sent by the computer to save user investment. In other words, if a PC is used to control the power system through GPIB interface, this option does not need to be purchased!
(2) Output isolation and polarity reversal: By sending programmable commands, the physical connection between the output terminal of the power module and the load can be disconnected, and the positive and negative poles of the power module output can be automatically swapped. This option is not recommended for high voltage or high current modules (such as DC176101, DC176101A, DC176108, DC176108A).
