Programmable Power Module
Part Number: QTL1999, QTL1995, QTL3358
Product Details
Replace your bench power supplies, scope, and current probes with a Programmable Power Module (PPM): a powerful and cost-effective alternative.
The PPM range is intended mainly for testing of SSDs, HDDs, and other PCIe, SAS, and SATA devices. Fixtures are available to allow many common devices to be instrumented in seconds.
Simple screw terminal fixtures are also available so you can test any device that fits within the power spec of the PPM.
The PPM has fast sampling for highly accurate power measurements and can record for hours or even days using Quarch Power Studio or our simple automation scripts.
The output voltages are fully controllable, allowing creation of complex ramp, glitch, and brownout patterns across both rails. Our patented multi-shunt mechanism allows seamless capture from 100uA to the peak supply of 9.2Amps
Trusted by major SSD manufacturers across the industry for over 10 years. Get the data you need to improve your products today!
NEW!: The MegaPPM (QTL3357) has arrived, 4x the sampling rate for 1MHz capture and increased power output to test the latest enterprise devices.

Features
This PPM is a flexible power margining and measurement tool. This version has 12V and 5V (switchable to 3V3) outputs and is ideal for SAS, SATA and PCIe-based devices. The outputs can be set automatically when used with advanced Quarch fixtures.
Each rail can be programmed from 0 to 120% of its nominal voltage. The voltage and current of each output can be simultaneously recorded to provide accurate power consumption measurement.
The module allows programming of arbitrary voltage output waveforms, which can be used to simulate power-up ramps, power failures, noisy power sources, and much more. Patterns can be created over a range of microseconds to minutes, allowing a wide range of testing options.
A high-speed record feature provides an oscilloscope-like function to record the output voltage, current, and power consumption of the attached device.
A range of injection fixtures allow the module to inject power into a variety of devices.

Servicing
Repair and calibration services are available from the Quarch offices in the UK. Contact your reseller for a quote.
A calibration service is also available in the US via Simco: https://www.simco.com/
It is possible to calibrate on your own lab and this may be useful for sites with many units. This requires a Keithley 2460 and a QTL2294 (Calibration switchbox kit)
