A 500 W industrial desktop power supply converts 110 V or 240 V AC to selectable 5 V, 12 V, 24 V or 36 V DC with built-in protection circuits
The NShi desktop server chassis integrates a 500 W AC-DC unit that accepts 110 V to 240 V mains and delivers selectable DC rails at 5 V, 12 V, 24 V or 36 V. It suits integrators assembling industrial or automation systems that need multiple voltages from a single metal enclosure.
The metal and aluminium shell operates from 0 °C to 40 °C with humidity up to 95 % non-condensing. Built-in over-voltage, over-current and short-circuit protection engages automatically, while CCC, RoHS and CE markings confirm compliance with recognised safety standards.
Four fixed output voltages are available simultaneously, with a combined current capability up to 60 A across the rails. Buyers who require a single high-current rail or programmable voltage steps should verify that the fixed 5 V, 12 V, 24 V and 36 V rails meet their load profile before ordering.

Mount the metal or aluminum case securely, then connect the AC 110V or 240V input to the supply terminals; the step most often missed is verifying that the DC output leads match the required 5V, 12V, 24V or 36V rails before powering on.
The built-in over-voltage, over-current and short-circuit protection reduces wear, but plan to inspect the internal fan and clean dust from the metal case vents periodically; replace the supply if output voltages drift outside the 0 to 60A range.
The working temperature ceiling of 40°C is the first limit; if ambient heat pushes the chassis above this, the protection circuits will shut the unit down before the 500W rating can be maintained continuously.
