The ITECH IT6953A is a single-channel, wide-range programmable DC power supply offering up to 150 V and 10 A with a maximum output of 600 W. Featuring autoranging, high resolution, list sequencing, timer control, built-in metering, and standard interfaces (RS‑232, USB, GPIB), it's ideal for automated test systems, R&D, and production labs..
The IT6953A is part of ITECH’s IT6900A series and features wide-range output control, allowing it to operate in both high-voltage/low-current and low-voltage/high-current scenarios. This makes it a versatile tool for testing electronic components, battery systems, and power modules.
It includes list-mode sequencing for multi-step programmable testing and a built-in timer for controlled duration output. Its built-in measurement capabilities reduce the need for external meters. Remote sensing ensures voltage accuracy at the device under test by compensating for lead losses.
Connectivity is robust, with RS‑232, USB, and GPIB available as standard interfaces. Intelligent fan cooling keeps the unit operating at stable temperatures, even under demanding conditions. Safety features are built-in to protect both the power supply and the device under test.
