Overview
High-Performance Mixed-Mode Power Supply for Professional Applications
The Picotest P9610A Mixed-Mode DC Power Supply represents a breakthrough in power supply technology, combining the high efficiency of switched-mode designs with the precision and low noise performance of linear regulators. This innovative 108W power supply delivers exceptional performance across its full operating range of 0-36V and 0-7A, making it an ideal choice for demanding electronic design and test applications.
Advanced Mixed-Mode Technology
At the heart of the P9610A lies Picotest's proprietary mixed-mode architecture, which uses a highly efficient switching converter for primary power conversion followed by a precision linear regulator for final output conditioning. This design approach delivers exceptional efficiency whilst maintaining the ultra-low noise characteristics essential for sensitive circuit testing. With ripple and noise as low as 1.26mV peak-to-peak across the 20Hz to 20MHz bandwidth, the P9610A outperforms traditional competitor solutions by 35%.
Continuous Autoranging Capability
Unlike conventional power supplies that require manual range switching, the P9610A features true continuous autoranging technology. This advanced capability ensures that 100% of the unit's 108W power is available across the entire voltage and current range, maximising flexibility and eliminating the need for multiple power supplies. The autoranging function seamlessly adjusts voltage and current parameters to deliver optimal power for any application within the specified limits.
Professional Features and Protection
The P9610A incorporates comprehensive protection systems including overvoltage protection (OVP), overcurrent protection (OCP), and over-temperature protection (OTP) to safeguard both the power supply and connected devices. The unit features an innovative optical adjustment knob that provides precise control without the degradation associated with traditional potentiometers. Remote sensing capability eliminates the need for shorting bars, whilst master-slave operation enables multiple units to be connected for higher voltage or current requirements.
The P9610A is also available as part of the P9610A series, which includes the higher power P9611A model offering 150W output capability at 60V/6A. Both models share the same advanced mixed-mode technology and professional feature set, providing scalable solutions for varying power requirements.

Questions and Answers
-
Can Multiple P9610A Units Be Connected Together?
Yes. The P9610A supports master-slave operation. Connect units in series for higher voltage (up to 252V with 7 units) or in parallel for higher current (up to 49A with 7 units).
-
What Programming Interfaces Are Available for the P9610A?
The P9610A is available with an optional USB interface or combined USB and GPIB interfaces for remote programming and control. It uses standard SCPI commands and is programming-compatible with the Keysight E3632A, so it fits into existing test systems.
-
How Fast Is the Transient Response of the P9610A?
Recovery time after a load change is less than 30 microseconds. This keeps the output voltage stable during rapid load changes, which helps when testing circuits with dynamic current demands.
-
What Applications Benefit Most From the P9610A's Capabilities?
The P9610A suits circuit design verification, production testing, quality assurance and research where low noise and high precision matter. It is particularly suitable for powering microprocessors, analogue circuits, precision measurement equipment and sensitive devices under test.
-
How Does the P9610A Compare to Higher-priced Competitive Solutions?
The P9610A has 35% lower noise than competitors, continuous autoranging and features usually found in more expensive linear supplies. It keeps the efficiency and compact size of a switching design, and costs less than traditional high-end linear supplies.
-
What Is Mixed-mode Technology, and How Does It Benefit the P9610A Power Supply?
Mixed-mode technology gives you the efficiency of a switching supply with the low noise and fast transient response of a linear supply. The P9610A has 35% lower noise than traditional competitors.
-
How Does Continuous Autoranging Differ From Conventional Power Supply Ranges?
Continuous autoranging lets the P9610A deliver its full 108 W across a range of voltage and current combinations, with no manual range switching. For example, it can supply 7 A up to about 15.4 V, or 36 V at up to 3 A. Conventional dual-range supplies reach full power only at the top of each range, so you must switch ranges to get it.
-
Can the P9610A Be Used with Sensitive Measurement Equipment?
Yes. The P9610A is designed for precision measurement work. In Picotest's own test its output noise measured about 1.26mV peak-to-peak from 20Hz to 20MHz (specified below 2mV peak-to-peak), so it suits sensitive analogue circuits, precision ADCs and other measurement equipment that needs clean power.
-
What Protection Features Are Included in the P9610A?
The P9610A includes:
- Overvoltage protection (OVP)
- Overcurrent protection (OCP)
- Over-temperature protection (OTP)
- Short-circuit withstand capability
These protect both the supply and connected devices under fault conditions.
-
How Does Remote Sensing Work Without Shorting Bars?
The P9610A has selectable internal compensation, so you don't need shorting bars when remote sensing isn't used. When you select external sensing (EXT) from the menu or over SCPI, the supply regulates the voltage at the load terminals, compensating for voltage drop in the cables.
