Complete Triple-Output Supply

Complete model PT-6503.
All three outputs CH1: 3.3 V DC at 6 A; CH2: 5 V DC at 6 A; CH3: 12 V DC at 1 A.
Combined rated output power 61.8 W for the complete three-output unit.
Typical efficiency 72%.
CH1 voltage adjustment 3 to 3.6 V.
Combined CH1 and CH2 limit 54 W maximum; total CH1 + CH2 + CH3 remains limited to 61.8 W.

The three channels form one complete power supply. Observe each channel’s minimum and maximum current and the combined output-power limits together. Individual maximum channel currents are not a simultaneous combined-power rating.

Production test 100% full-load burn-in.

Unless specified otherwise, parameters are measured at 230 VAC, rated load and 25°C ambient. Ripple and noise are measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Voltage tolerance includes set-up tolerance, line regulation and load regulation.

Protection

Short circuit / overload 120–160% of rated output power. Hiccup mode; automatic recovery after the fault condition is removed.
Overvoltage threshold CH2 (+5 V): 5.75–6.75 V.
Overvoltage response Hiccup mode; automatic recovery after the fault condition is removed.

Cooling, Load Derating and Environment

Working temperature −10 to +60°C, subject to the applicable horizontal-installation derating curve.
Natural-convection curve 80% load at −10°C, rising to 100% at 0°C; full load through 30°C, then decreasing to 40% at 60°C.
Forced-air thermal curve With at least 18 CFM: 80% at −10°C, 100% at 0°C through 50°C, then 60% at 60°C. This does not increase the 61.8 W combined maximum or the 54 W CH1 + CH2 limit.
Working humidity 20–90% RH, non-condensing.
Storage conditions −20 to +85°C; 10–95% RH.
Temperature coefficient ±0.03%/°C over 0–50°C.
Vibration 10–500 Hz, 2 G; 10-minute cycle, 60 minutes along each X, Y and Z axis.
High-altitude temperature adjustment Above 2000 m, reduce allowable ambient temperature by 3.5°C per 1000 m for fanless operation, or 5°C per 1000 m for fan-cooled operation.

Keep airflow unobstructed and apply the load limits for the actual mounting orientation and cooling conditions.

Mechanical Installation and Grounding

Dimensions, L × W × H 127 × 76 × 42 mm.
Drawing tolerance ±1 mm.
Mounting holes Four Ø3.8 mm holes, with 115.8 × 64.8 mm centre spacing and 5.6 mm edge references.
