Model and output specifications

Output voltage ±12 V DC relative to COM.
Rated output current 1250 mA per output rail.
Series power and load limit 30 W. Observe the current and total output-power limits together.
Minimum load No minimum load is required.
Voltage accuracy ±2.0% maximum
Line regulation ±0.2%; low-to-high input at rated load.
Load regulation ±0.5%, measured over 0–100% load.
Ripple and noise 150 mVp-p maximum. Measured at 20 MHz bandwidth with a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
Switching frequency 380 kHz typical.
Maximum capacitive load 150 µF for each output.

Input, control and protection

Input voltage 9–36 V DC; 4:1 range. Nominal inputs 12 and 24 V.
Input current 28 mA at no load; 2850 mA at full load, at 12 V input.
Typical efficiency 87% at the reference conditions.
Input filter and fuse Pi filter. The manufacturer recommends a 6 A slow-blow external fuse; select it for the actual input and installation.
Overload protection 110–230%; automatic recovery after the fault is removed.
Short-circuit protection Continuous protection with automatic recovery.
Input overvoltage protection Input shutdown at 40 V DC typical.
Output overvoltage protection Clamped by TVS.
Remote ON/OFF Referenced to −Vin: >2.5–5 V or open circuit turns the output ON; <1 V or a short circuit turns it OFF.
Configuration This model uses the standard pin type; ST is the separately identified screw-terminal configuration.
Other output options A 24 V single-output option is mentioned in the catalog; obtain its complete order code and specifications from the manufacturer.

Operating conditions and isolation

Operating temperature and cooling −40 to +90°C; free-air convection. Apply the load-derating limits.
Load derating Full load through 60°C; 50% at 80°C; 25% at 90°C.
