ITECH IT6300 Series Alternative: Triple Output DC Power Supply Comparison
The ITECH IT6300 series (like the IT6322) is well-known for its high-performance programmable triple output DC power supplies. However, for labs looking to maximize their budget without sacrificing 4-digit precision or SCPI automation, the eTM-DM series offers a highly competitive alternative.
When outfitting an electronics lab, the ITECH triple output dc power supply is often considered a premium choice. Models like the IT6322 offer excellent specifications, but they come with a premium price tag. Let's compare the core specifications of the ITECH IT6322 against the eTM-3030DM to see if the premium is justified for your specific application.
| Feature | ITECH IT6322 (Typical) | eTM-3030DM (Alternative) |
|---|---|---|
| CH1 & CH2 Output | 0-30V / 0-3A | 0-30V / 0-3A |
| CH3 Output | 0-5V / 0-3A | 0-5V / 0-3A |
| Display Resolution | 1mV / 1mA | 1mV / 1mA (4-Digit) |
| Ripple & Noise | < 1mVrms | < 1mVrms |
| Interfaces | USB / RS232 / GPIB (Optional) | USB / RS232 / RS485 |
| SCPI Support | ||
| Estimated Price | ~$1,200+ | ~$449 |
Why Choose the eTM-DM Series?
- Identical Core Specs: For 95% of bench testing, the 30V/3A and 5V/3A channel configuration with 1mV/1mA resolution is exactly what engineers need. The eTM-DM matches this core requirement perfectly.
- Cost-Effective Automation: Both units support SCPI commands via USB/RS232. If your goal is to build an automated test rack, the eTM-DM allows you to buy two or three units for the price of one ITECH, massively increasing your test throughput.
- No Hidden Fees: Some premium brands charge extra for communication interfaces or higher resolution unlocks. The eTM-DM series comes fully unlocked out of the box.
The Verdict
If your application requires highly specialized features, ultra-fast transient recovery times, or native GPIB integration, the ITECH IT6300 series is a phenomenal instrument. However, if you need a reliable, high-precision, programmable triple output DC power supply for standard R&D, education, or production testing, the eTM-DM series offers unbeatable value.
