Phoenix Contact QUINT4-PS/24DC/12DC/8/PT - DC/DC converter

The Phoenix Contact QUINT4-PS/24DC/12DC/8/PT (Part Number: 2910122) brings industrial-grade performance to control cabinets, offering reliable voltage conversion, isolation, and system protection in one compact unit. Equipped with SFB (Selective Fuse Breaking) technology and smart signaling, it ensures maximum uptime in demanding environments.

Key Specifications

Input & Output Characteristics

• Stable input: Requires a nominal 24 V DC (−25%/+40% range), not wide-range input.

• Reliable buffering: ~17 ms hold-up time at 24 V DC. 

• Built-in protection: Internal 15 A slow-blow fuse and low inrush current (< 3 A typical, < 0.02 A²·s) for system safety.

• Output: 12 V DC up to 8 A with adjustable range up to 15 V DC. 

• Boost modes:

  • Static Boost up to 10 A

  • Dynamic Boost up to 16 A for 5 seconds

  • Selective Fuse Breaking (SFB) delivers a powerful 48 A for 15 ms, enabling quick tripping of downstream breakers.

• Efficiency: Around 91% operates efficiently, minimizing heat. 

• Output quality: Ultra-low ripple (< 13 mVpp), control deviation < 1%, rapid voltage rise (< 100 ms). 

• Power handling:

  • Nominal: 96 W

  • Static Boost: ~120 W

  • Dynamic Boost: ~192 W for up to 5 seconds

Diagnostics & Signaling

• LED indicators: Show power load levels and voltage status (green/yellow/flashing behavior to signal normal, high load, or fault conditions).

• Configurable signal outputs:

  • Out1 & Out2: Digital and analog (4–20 mA) outputs for monitoring input/output power, voltage, current, operating hours, overvoltage, or thermal warning.

  • Relay output: Floating contact (1 A / 30 V AC or 0.5 A digital) for additional alerts or control.

  • Remote control input: Allow remote ON/OFF control.

Reliability & Safety

• Strong isolation: 4 kV DC type-tested; 2 kV routine-tested between input and output.

• MTBF: > 970,000 h at 40 °C, ensuring long operational life.

• Rugged housing: IP20 rated, V0 flammability, metal construction with stainless steel and aluminum elements. 

• Environmental range:

  • Operating: −25 °C to +70 °C (derating above 60 °C at 2.5%/K)

  • Shock and humidity rated for challenging industrial conditions. 

• Certifications: UL, cUL, railway and marine approvals, hazardous-location Class I Division 2.

Dimensions & Connections

• Size: 36 mm (W) × 130 mm (H) × 125 mm (D) in normal orientation; rotates for different mounting configurations.

• Connectivity: Push-in terminals support 0.2–6 mm² (AWG 24–10) conductors; separate ports for input, output, and signaling.
