Model and output specifications

Parameter Specification
Complete model DCW12C-12
Model selection DCW12 identifies the 12 W regulated dual-output converter series. Input code C selects the 36–72 V DC operating range. Suffix 12 identifies the ±12 V output.
Output voltage +12 V and −12 V relative to COM.
Output current range 100–500 mA on each output rail (catalog notation: ±100 to ±500 mA). Observe the stated minimum load and the combined rated-power limit.
Rated power 12 W total across the two outputs.
Voltage accuracy ±2.0%.
Line regulation ±0.5%, measured from low to high input voltage at rated load.
Load regulation ±0.5%, measured over 20–100% of rated load.
Ripple and noise 60 mVp-p maximum, measured with 20 MHz bandwidth and a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
External capacitance load 100 µF maximum, as listed for this output voltage.
Switching frequency 400 kHz minimum.

Input and protection

Parameter Specification
Input voltage 36–72 V DC, 2:1 input range.
Input current 320 mA at full load; 25 mA at no load, at the nominal input condition.
Typical efficiency 84%.
Input filter and protection Built-in EMI filter with a pi-network input filter. An input fuse is recommended.
Remote ON/OFF control Pin 1 (R.C.) is referenced to −Vin. Power ON: R.C. to −Vin > 4 V DC, or leave R.C. open. Power OFF: R.C. to −Vin < 1 V DC, or short R.C. to −Vin.
Overload protection Activates within 110–180% of rated output load. Hiccup mode, with automatic recovery after the fault is removed.
Short-circuit protection All outputs have overcurrent protection; hiccup operation recovers automatically after the fault is removed.
Fault duration limit Do not operate the converter in overload or short circuit for more than 30 seconds.

Isolation and operating conditions

Parameter Specification
Input-to-output withstand voltage 1.5 kV DC (1500 V DC).
Insulation resistance 100 MΩ between input and output, measured at 500 V DC, 25°C and 70% RH.
Isolation capacitance 2200 pF maximum between input and output.
Operating temperature and cooling −40 to +71°C with free-air convection. The derating curve shows 100% load through +60°C, then decreases to 60% at +71°C. Do not extend the operating range beyond +71°C from the further continuation of the graph.
Working humidity 20–90% RH, non-condensing.
Storage conditions −40 to +105°C; 10–95% RH.
Temperature coefficient ±0.05%/°C over 0–50°C.
Vibration 10–500 Hz at 2G; 10 minutes per cycle, for 60 minutes along each of the X, Y and Z axes.
Reference test conditions Unless otherwise specified, ratings are measured at nominal input, rated load, 25°C and 70% RH.

Mounting, connections and reference data

Parameter Specification
Construction and cooling Five-sided shielded metal case with free-air convection cooling.
Dimensions 31.8 × 20.3 × 12.2 mm (L × W × H); use the mechanical drawing for PCB layout and pin spacing.
Pin assignment Bottom-view numbering: pins 2 and 3 = −Vin; pins 22 and 23 = +Vin; pins 9 and 16 = COM; pin 11 = −Vout; pin 14 = +Vout. Pin 1 = R.C. (remote control).
Unit weight reference 17.5 g per converter, as stated in the catalog packing entry.
Safety and EMC EAC TP TC 020/2011 approved. EMC emission: BS EN/EN 55032 Class A, FCC Part 15 Class A and EAC TP TC 020. Immunity: BS EN/EN 61000-4-2, -3, -4, -5, -6 and -8, light-industry level, criteria A, and EAC TP TC 020.
Reliability reference MTBF: 600 khrs minimum to MIL-HDBK-217F at 25°C. The manufacturer specifies 100% full-load burn-in testing. MTBF is a reference reliability figure.
Manufacturer warranty reference The catalog states a 2-year manufacturer warranty.
