Sag immunity testing in our Lab

In-house services

Voltage sag immunity testing, certification, Training
Design review and advice - power portion of semiconductor tools

We specialize in SEMI F47, SEMI E6, SEMI S23, IEEE 1100, and IEC 61000-4-30 certification,
and we are glad to provide firm, fixed-price quotations.
Virtually every major supplier of power supplies to the semiconductor industry, and every major contactor manufacturer, uses Power Standards Lab for SEMI F47 certification.

Contact us, and we will get started on your project.

Calibration standards at PSL
PSL's ultimate resistance standard:
0.09999863 ohms

In-house Calibration Standards

0.01% 50Vrms - 500Vrms source, 45 Hz - 200 kHz
0.02% 0.1 - 2.5Arms source
0.0001% 10.0000 Vdc source
0.001% Decade resistors from 0.1 ohms to 1 Megohm
0.1% true RMS voltmeters and current meters
Digital oscilloscopes, including 1kV and 10kV probes

For calibration, PSL maintains two ultra-accurate references: a 0.1 ohm resistor (actually 0.09999863 ohms), and a 1 volt source (actually 1.00000096 volts).
We use these references individually to calibrate our calibration instruments, and we combine them to generate reference currents.

Our references are periodically calibrated at NIST directly against the United States National Working Standards.
For calibrating higher AC voltages -- one of our particular interests -- we use a calibration-grade ratio transformer to bring the unknown voltage into our calibration range.
