MEAN WELL DLW05 series: Isolated regulated dual-output DC-DC converter - DLW05B-12

Description

DLW05B-12 — Isolated regulated dual-output DC-DC converter

MEAN WELL DLW05B-12 is an isolated, regulated dual-output DC-DC converter with ±12 V DC output relative to the Common return and a specified current range of 20.8–208 mA per output rail. Its 2 × 1 inch package accepts 18–36 V DC and provides 1.5 kV DC input-to-output isolation. It uses a built-in EMI filter and a metal case with shielding on all six sides.

Model and output specifications

Complete model DLW05B-12
Model selection DLW05 identifies the 5 W dual-output series. Input code B selects 18–36 V DC; output code 12 selects ±12 V DC.
Output voltage ±12 V DC relative to Common; positive and negative output rails.
Output current range 20.8–208 mA per output rail. Maintain the specified minimum load.
Rated power and load limit 5 W total across both output rails. Observe the stated current limits and total power limit together.
Voltage accuracy ±2.0%.
Line regulation ±0.2%, measured from low to high input voltage at rated load.
Load regulation ±0.5%, measured over 10–100% of rated load.
Ripple and noise 60 mVp-p maximum, measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
Switching frequency 50 kHz minimum.

Input and protection

Input voltage 18–36 V DC; 2:1 input range.
Input current 16 mA at no load; 270 mA at full load, at the reference test conditions.
Typical efficiency 82% at the reference test conditions.
Input filter and protection Built-in EMI filter with a Pi network. An external input fuse is recommended.
Overload protection 160–250% of rated output power; hiccup mode with automatic recovery after the fault is removed.
Short-circuit protection All outputs are protected; hiccup mode with automatic recovery after the fault is removed.
Fault-duration limit Do not allow operation in overload or short circuit for more than 30 seconds.
Optional configurations The catalog lists 4:1 input-range and 3 kV isolation options. The stated model specifications are 2:1 and 1.5 kV; confirm any optional configuration with the manufacturer before selection.

Operating conditions and isolation

Operating temperature and cooling −25 to +71°C, with free-air convection and the specified derating.
Load derating Full load through 60°C, with load derating above 60°C. Apply the curve only within the specified working range up to 71°C.
Working humidity 20–90% RH, non-condensing.
Storage conditions −25 to +105°C; 10–95% RH, non-condensing.
Temperature coefficient ±0.03%/°C over 0–50°C.
Vibration 10–500 Hz, 2G; 10 minutes per cycle for 60 minutes along each of the X, Y and Z axes.
Reference test conditions Normal input, rated load, 25°C ambient and 70% RH, unless otherwise stated.
Input-to-output withstand voltage 1.5 kV DC.
Isolation resistance 100 MΩ at 500 V DC, 25°C and 70% RH.

Mechanical design and installation

Dimensions 50.8 × 25.4 × 11.27 mm (L × W × H), as listed in the specification.
Case and production testing Metal case with shielding on all six sides; 100% burn-in test. The catalog describes a low-cost design with an emphasis on reliability.
Pin assignment 1 +Vin; 2 −Vin; 3 +Vout; 4 COM; 5 −Vout. Check the bottom-view orientation before PCB assembly.
Mechanical drawing details Pin diameter: 0.8 mm (+0.2/−0 mm). Lead length: 5.8 mm. Use the bottom-view drawing for the unequal spacing and PCB orientation.
Unit weight reference 31.2 g per converter, explicitly stated in the catalog packing entry.

EMC and manufacturer references

Safety standards EAC TP TC 020/2011 approved.
Catalog approvals FCC, EAC, CE and UKCA are listed in the manufacturer’s features.
EMC emission BS EN/EN 55032 Class B, FCC Part 15 Class B, and EAC TP TC 020.
