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.

The P9610A excels in circuit design verification, production testing, quality assurance, and research applications where low noise and high precision are essential. It's particularly suitable for powering microprocessors, analogue circuits, precision measurement equipment, and sensitive electronic devices under test.
-
How fast is the transient response of the P9610A?
The P9610A features excellent transient response with recovery times of less than 30 microseconds following load changes. This fast response ensures stable output voltage even during rapid load variations, making it ideal for testing circuits with dynamic current demands.
-
What programming interfaces are available for the P9610A?
The P9610A is available with optional USB interface or combined USB and GPIB interfaces for remote programming and control. The unit uses standard SCPI commands and is programming-compatible with the Keysight E3632A, ensuring easy integration into existing test systems.
-
Can multiple P9610A units be connected together?
Yes, the P9610A supports master-slave operation allowing multiple units to be connected in series for higher voltages (up to 252V with 7 units) or parallel for higher current (up to 49A with 7 units). This modular approach provides scalable power solutions for demanding applications.
-
How does remote sensing work without shorting bars?
The P9610A features selectable internal compensation that eliminates the need for traditional shorting bars when remote sensing is not required. When remote sensing is needed, the internal circuit automatically adjusts to provide accurate voltage regulation at the load terminals, compensating for voltage drops in connection cables.
-
What protection features are included in the P9610A?
The P9610A incorporates comprehensive protection including overvoltage protection (OVP), overcurrent protection (OCP), over-temperature protection (OTP), and short-circuit withstand capability. These features protect both the power supply and connected devices from damage due to fault conditions.
-
Can the P9610A be used with sensitive measurement equipment?
Yes, the P9610A is specifically designed for precision measurement applications. Its ultra-low noise output of 1.26mV peak-to-peak across 20Hz to 20MHz makes it ideal for powering sensitive analogue circuits, precision ADCs, and other measurement equipment where clean power is critical.
-
How does continuous autoranging differ from conventional power supply ranges?
Continuous autoranging provides 100% power availability across the entire voltage and current envelope without manual range switching. Unlike conventional supplies that limit power at certain voltage/current combinations, the P9610A automatically optimises its output parameters to deliver maximum power for any setting within the 36V/7A limits.
-
What is mixed-mode technology, and how does it benefit the P9610A power supply?
Mixed-mode technology combines a switched-mode pre-regulator with a linear final stage, delivering the efficiency advantages of switching supplies whilst maintaining the low noise and fast transient response of linear regulators. The P9610A achieves 35% lower noise than traditional competitors whilst maintaining high efficiency across its operating range.
