MEAN WELL DKE15 series: Isolated regulated dual-output DC-DC converter - DKE15A-05

Description

DKE15A-05 — Isolated regulated dual-output DC-DC converter

MEAN WELL DKE15A-05 is an isolated dual-output DC-DC converter accepting 9–18 V DC. It provides ±5 V DC relative to the Common return, with 15 W total rated output power. The specified current range is 150–1500 mA per output rail; maintain the minimum loads and the combined power limit. Its 2 × 2 inch metal package provides 1.5 kV DC input-to-output isolation.

Model and output specifications

Complete model DKE15A-05
Model selection DKE15 identifies the dual-output series. Input code A selects 9–18 V DC. Output code 05 selects ±5 V DC.
Output voltage ±5 V DC relative to Common. Positive and negative output rails share the Common return.
Output current range 150–1500 mA per output rail. Maintain the stated minimum current on each output.
Rated power and load limit 15 W total across all two output rails. Observe every rail current limit and the combined output-power limit together.
Voltage accuracy ±2.0%.
Line regulation ±0.3%, 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.
Switching frequency 150 kHz minimum.

Input and protection

Input voltage 9–18 V DC; 2:1 input range.
Input current 1700 mA at full load; 40 mA at no load, at the reference test conditions.
Typical efficiency 81% 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 a 4:1 input-range option and a 3 kV DC input-to-output isolation option. The stated specifications for this model are 2:1 and 1.5 kV DC; confirm the 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 load derating.
Load derating Full load through 60°C; reduce to 80% load at 71°C. Apply the curve only within the specified operating range.
Working humidity 20–90% RH, non-condensing.
Storage conditions −25 to +105°C; 10–95% RH.
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 × 50.8 × 11 mm (L × W × H).
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: 1.0 mm (+0.2/−0.1 mm); lead length: 5.8 mm. Bottom-view drawing: output-side spacing is 10.20 mm; the input pins are separated by 5.10 mm. Follow the complete drawing for the asymmetric pin positions.
Unit weight reference 60 g, explicitly stated as a catalog packing reference per unit. Tube and carton gross weights are separate packaging data.

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 A; FCC Part 15 Class A; EAC TP TC 020.
EMC immunity BS EN/EN 61000-4-2, -4-3, -4-4, -4-5, -4-6 and -4-8; light-industrial level, criterion A; EAC TP TC 020.
MTBF reference 300 khrs minimum to MIL-HDBK-217F at 25°C; a reliability reference, not a service-life guarantee.
