Model and output specifications

Parameter Specification
Complete model DKMW15F-12
Output configuration Dual regulated outputs with a Common return.
Output voltage ±12 V DC.
Output current range 0–625 mA per output rail. No minimum load is required.
Rated power and load limit 15 W series rating. Observe both the output-current limits and the rated total power.
Voltage accuracy ±2%.
Line regulation ±0.5%, measured from low to high input voltage at rated load.
Load regulation ±0.5%, measured over 10–100% of rated load.
Ripple and noise 50 mVp-p maximum, measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
Maximum capacitive load 470 µF per output.
Typical switching frequency 300 kHz.

Input and protection

Parameter Specification
Input voltage 9–36 V DC; 4:1 range. Nominal input voltage: 24 V DC.
Input current 35 mA at no load; 730 mA at full load, at the reference test conditions.
Typical efficiency 88% at the reference test conditions.
Input filter and fuse Pi-type input filter. Recommended external fuse: 4 A, time-delay/slow-blow type.
Short-circuit protection Continuous protection with automatic recovery.
Overload protection 110–220% of rated output power; recovers automatically after the fault is removed.
Overvoltage protection Hiccup mode.
Input undervoltage lockout Start-up threshold: 9 V DC; shutdown threshold: 8.6 V DC. These do not extend the normal input-voltage range.

Control and adjustment

Parameter Specification
Remote ON/OFF control R.C. is referenced to −Vin. Power ON: Above 2.5 V up to 6 V, or open circuit. Power OFF: Below 0.5 V, or short circuit.
Output trim The specified external trim function is for single-output models. This dual-output model uses Common in place of the trim connection.

Operating conditions and isolation

Parameter Specification
Operating temperature and cooling −40 to +85°C, with free-air convection and load derating.
Load derating Natural convection: 100% load through +71°C, reducing to 50% at +85°C. Keep ambient temperature within the specified −40 to +85°C operating range.
Maximum case temperature +110°C; this is the case limit, not an ambient-temperature rating.
Working humidity 5–95% RH, non-condensing.
Storage conditions −55 to +125°C; 10–95% RH, non-condensing.
Temperature coefficient 0.03%/°C over 0–71°C.
Vibration 10–500 Hz, 2G; 10 minutes per cycle, 60 minutes along each of the X, Y and Z axes.
Input-to-output withstand voltage 3 kV DC (3000 V DC).
Isolation resistance 100 MΩ between input and output, at 500 V DC, 25°C and 70% RH.
Typical isolation capacitance 1200 pF between input and output.
Reference test conditions Unless otherwise specified: normal 24 V DC input, rated load, 25°C and 70% RH.

Dimensions and PCB installation

Parameter Specification
Package and construction DIP 1 × 1 inch package with industry-standard pinout. Black-coated metal case with a non-conductive base.
Dimensions 25.4 × 25.4 × 10.2 mm (L × W × H).
Pin assignment 1 +Vin; 2 −Vin; 3 Remote ON/OFF; 4 −Vout; 5 Common; 6 +Vout. Check the bottom-view pin drawing against the top-view PCB footprint.
PCB layout Pin diameter: 1 ±0.1 mm. Lead length: 5.8 ±0.5 mm. PCB hole diameter: 1.2 mm (+0.2/−0.1 mm). Use the datasheet footprint for the unequal pin spacing, 2.54 mm grid and 20.32 mm spacing between pin rows.
Soldering limit 3–5 seconds at 265°C maximum, measured 1.5 mm from the case.
Unit weight reference 20 g, catalog packing reference per unit.
Catalog packing 10 pieces per tube; 600 pieces per carton.

EMC and reference information

Parameter Specification
Safety standards EAC TP TC 020/2011 approved.
EMC emission conditions Conducted emissions: N/A in the table. Radiated emissions: Class A without external components; Class B with the specified external circuit, BS EN/EN55032 (CISPR32). Verify the completed equipment against the applicable EMC requirements.
External EMC circuit Radiated Class B reference: C1 and C2 = 4.7 µF / 50 V; C3 = 1000 pF / 3 kV; common-mode choke L1 = 325 µH. Use the complete datasheet circuit; these are external design components, not an included kit.
EMC immunity BS EN/EN 61000-4-2: ±4 kV contact; -4-3: 3 V/m; -4-4: ±0.5 kV with the referenced circuit; -4-5: ±0.5 kV line-to-line; -4-6: 3 Vrms.
