Frequently Asked Questions
Have a Question?
-
How does the display and front-panel operation compare to modern instruments?
The vacuum-fluorescent display provides excellent visibility in all lighting conditions and simultaneously shows voltage and current for the selected channel. While not a colour LCD, the interface is intuitive with dedicated function keys and rotary encoder for precise adjustments.
-
What protection features prevent damage to my circuits under test?
Built-in over-voltage protection (OVP), over-current protection (OCP), and over-temperature protection (OTP) automatically shutdown outputs when limits are exceeded. You can set custom voltage and current limits below maximum ratings for additional circuit protection.
-
Can I store and recall different power supply configurations quickly?
Yes, the 3631A stores up to 10 complete operating states in non-volatile memory. Each state includes all three channel settings, tracking mode, and limit values. Use the Store/Recall buttons for instant configuration changes during testing sequences.
-
How accurate are the voltage and current settings compared to premium alternatives?
Programming accuracy is 0.05% + 20mV for ±25V outputs and 0.1% + 5mV for the 6V output. This matches or exceeds many premium instruments costing significantly more, making the 3631A excellent value for precision applications.
-
What remote control interfaces are available and do I need special software?
Standard interfaces include USB and RS-232, with optional GPIB. The 3631A supports industry-standard SCPI commands, making it compatible with LabVIEW, MATLAB, Python, and other programming environments. No proprietary software is required for basic remote operation.
-
How does the 6V channel isolation benefit my applications?
The 6V channel is completely electrically isolated from the ±25V channels, preventing ground loops and interference between digital and analogue circuits. This isolation allows you to power different circuit sections without interaction, essential for mixed-signal designs.
-
What makes the Array 3631A different from switching power supplies?
Can I use the ±25V outputs independently or do they always track together?
-
Can I use the ±25V outputs independently or do they always track together?
The ±25V outputs can operate independently or in tracking mode. Press the Track button to enable/disable symmetric tracking. In tracking mode, both outputs maintain ±(0.2% + 20mV) accuracy. You can also connect them in series for 0-50V/1A operation.
