150V 12A programmable bench supply

The Matrix MPS-1800S-150-12 is a programmable DC bench supply delivering up to 150 volts and 12 amps for 1800 watts of adjustable output. It targets engineers, test technicians and laboratory staff who need precise voltage and current control in a single bench-top unit.

AC 220V input with protection suite

The unit accepts single-phase AC 220 volts ±10 percent at 50 Hz and uses PWM modulation with a high-gain amplification circuit for stable operation. Built-in OVP, OCP, OTP and short-circuit protection guard both the supply and the load during abnormal conditions.

RS-232 and RS-485 remote interfaces

Dual serial interfaces allow automated voltage and current programming from a host computer or PLC. Front-panel preset buttons and a key-lock function speed repetitive test sequences while preventing accidental changes during long runs.

Questions about this item

How do I rack-mount the MPS-1800S-150-12 and what clearance mistake should I avoid?

The unit is 3.5 inches high (2U) and 19 inches wide, so it fits a standard 19-inch rack; leave at least 2 inches of rear clearance for the AC inlet and exhaust airflow, otherwise the over-temperature protection will trip under sustained load.

Which components will need replacement after continuous operation at 150 V and 12 A?

The internal cooling fan and the electrolytic capacitors on the PWM board are the first wear items; plan to inspect the fan annually and replace capacitors at the three-year mark when running at full 1800 W output.

What limit appears first when the supply runs at 1800 W for long periods?

Over-temperature protection engages once the internal heatsink exceeds its threshold, cutting output before the over-current or over-voltage circuits activate.
