Phoenix DEK-OE Series: Isolated DC/AC-DC Converters & Signal Transmitters - Selection Guide

Product Overview

The Phoenix DEK-OE Series comprises industrial-grade isolated converters and high-frequency signal transmitters designed for voltage conversion, signal isolation, and reliable power supply in automation systems. Supporting diverse input types (AC/DC) and output voltages (5V DC, 24V DC, 48V DC), these modules offer core functions like galvanic isolation (up to 3kV), high-frequency signal transmission (100kHz), and flexible terminal configurations. With variants for standard conversion, high-frequency (KHZ) signal handling, enhanced performance (G-suffixed), and specialized terminals (SO 46, T), they’re ideal for powering sensors, converting voltage domains, and transmitting noise-free signals in manufacturing, process control, and industrial electronics.

• Requirement: 24V DC to 48V DC step-up conversion (dual versions)

• Recommended Models: 5100345 (CH02), 5100316 (CH01)

• Key Reason: CH01/CH02 variants for application-specific compatibility; 3kV isolation

2. High-Speed Signal Transmission (100kHz)

• Requirement: 24V DC isolated high-speed signal transmission

• Recommended Models: 2964348 (G-enhanced), 2964283 (standard)

• Key Reason: 100kHz frequency for fast data/power delivery; G-variant suppresses EMI

• Recommended Model: 2964270 (DEK-OE-5DC/24DC/100KHZ)

• Key Reason: High-frequency design ideal for time-sensitive sensors/actuators

3. High-Voltage DC to 48V DC Conversion

• Requirement: 220V DC/110V DC high-voltage to 48V DC power
• Recommended Models: 5100361 (220DC/CH02), 5100329 (110DC/CH01)
• Key Reason: Handles high-input DC voltages; isolated output protects 48V DC devices

4. Low-Voltage Step-Up Conversion

• Requirement: 5V DC/12V DC to 48V DC low-power supply
• Recommended Models: 2940223 (5DC), 2964487 (12DC)
• Key Reason: Step-up conversion for low-voltage sources; 3kV isolation ensures safety

Core Advantages

• High-Frequency Capability: 100kHz models enable fast signal/power transmission for time-sensitive applications
• Enhanced Isolation: 3kV galvanic isolation eliminates noise and protects sensitive equipment
• Flexible Terminal Options: SO 46, T-terminals, and standard screw terminals fit diverse wiring setups
• EMI Suppression: G-suffixed models reduce electromagnetic interference in noisy industrial environments
• Dual Version Support: CH01/CH02 variants adapt to specific application requirements
• Industrial-Grade Durability: -25℃~70℃ operating temperature and IP20 protection resist harsh conditions

Installation & Usage Notes

• Voltage Matching: Ensure input voltage aligns with the module’s rating (e.g., 230AC models avoid DC input)
• High-Frequency Wiring: For KHZ models, use shielded cables and keep wire lengths ≤0.3m to maintain signal integrity
• Terminal Selection: Choose SO 46/T-terminal models based on existing cabinet terminal compatibility
• Mounting Spacing: Reserve ≥5mm between modules for heat dissipation, especially for high-frequency models
• Load Limitation: Do not exceed 100mA output current; use parallel modules for higher current needs
• EMI Mitigation: Deploy G-suffixed models near motors/inverters to suppress electromagnetic interference
• Polarity Attention: DC input models require correct polarity; reverse polarity protection is not universal (check datasheet)
