Description
Product Resume
This power supply is ideally suited for use with amplifier projects. The regulated 12VDC, 29A design is capable of delivering 350watts of output. Overload, over voltage, and over temperature protection is built-in, shutting down the power supply to prevent damage and then restoring power upon recovery.

| NOTE | 1. All parameters NOT specially mentioned are measured at 230VAC input，rated load and 25°C of ambient temperature.2. Ripple & noise are measured at 20MHz of bandwidth by using a 12’’ twisted pair-wire terminated with a 0.1μf & 47μf parallel capacitor.3. Tolerance: includes set up tolerance, line regulation and load regulation.4. Line regulation is measured from low line to high line at rated load.5. Load regulation is measured from 0% to 100% rated load.6. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.7. The 150% peak load capability is built in for up to 1 second for 12~48V. LRS-350 will enter hiccup mode if the peak load is delivered for over 1 second and will recover once it resumes to the rated current level (115VAC/230VAC).8. The ambient temperature derating of 5°C/1000m is needed for operating altitude greater than 2000m (6500ft). | |
