✅ 일반적인 애플리케이션

Control cabinets with 400V two-phase power supply, 위험한 장소, construction machinery, 공조, wind turbine auxiliary control systems; power supply for PLCs, 근접 스위치, solenoid valves and HMIs.

Important distinction: Unlike conventional single-phase 220V UNO power supplies, this model is a high-voltage two-phase input version, which is frequently misselected on site.

✅ Replacement Reference

Single-phase counterpart in the same series: 2902994 (UNO-PS/1AC/24DC/90W/C2LPS), input range 85–264 V AC. Do not interchange the two models.

For higher power with the same structure: UNO 150W & 240W two-phase variants.

✅ 문제 해결 가이드

1. DC OK indicator off: First verify two-phase input voltage. The unit will not start under phase loss or input voltage below 264 뷔와.
2. Excessive voltage drop under load: Check for overcurrent or temperature-induced derating.
3. Frequent protection trips: Load short circuit or output earth fault. 수업 2 models feature highly sensitive short-circuit protection.

피닉스 2904371 (UNO-PS/2AC/24DC/90W/C2LPS) 설치 매뉴얼

안전 전제조건: Indoor cabinet mounting only, IP20 등급. C2LPS stands for Class 2 output plus Class I Division 2 위험 지역 인증. All installation in explosive environments must comply strictly with ISA-12.12.01 standards.

1. 제품개요

주문번호: 2904371

시리즈: UNO POWER 2-phase DIN rail power supply

입력: 2-phase AC 264–575 V (400V two-phase, NOT single-phase 220V)

산출: 24 DC에서, 3.75 에이 / 90 여, adjustable 24–28 V

설치: NS35 DIN rail (EN60715), horizontal installation

하우징 폭: 55 mm

2. Clearance Requirements (Mandatory for Heat Dissipation)

Side-by-side horizontal installation: 0 mm minimum clearance (units may be mounted tightly together)

Vertical stacking: Minimum 30 mm upper and lower clearance for cooling air flow

No upside-down or side mounting; only horizontal installation with terminals facing forward/downward

Do not install adjacent to heat-generating components (접촉기, 제동 저항기); high ambient temperature will trigger power derating

Altitude derating: Power rating and insulation voltage must be reduced above 2000 m elevation

3. DIN Rail Installation & 제거
4. Hook the top latch onto the NS35 rail first
5. Press down the unit until the latch clicks securely into place
6. 제거: Insert a flat screwdriver into the bottom latch tab, pry upward to release the lock and pull the unit off the rail

진동 저항: Compliant with industrial cabinet vibration standards; no extra locking screws required once clipped firmly.

4. 배선사양 (M3 Screw Terminals)

터미널 유형: Screw clamping terminals

도체 크기: Solid wire 0.2–2.5 mm²; stranded wire 0.2–2.5 mm²; AWG24～AWG14

Strip length: 8 mm

Cable temperature rating: ≥75℃ for ambient <55℃; ≥90℃ for 55~70℃ ambient

조임 토크: 0.5–0.7 Nm (스레드 손상을 방지하려면 과도하게 조이지 마십시오.)

터미널 정의 (비판적인: Two-phase input, no neutral N!)

입력 단자: L1, L2 (two-phase 400V AC, neutral N is not connected); PE protective earth terminal

출력 단자: +24 다섯, 0 다섯 (24 DC에서)

Adjustment potentiometer: ADJ (24~28 V fine-tuning; 공장 사전 설정 24 다섯)

지시자: DC OK (green light ON = normal output; OFF = no output or protection active)

⚠️ Critical Warning: This is a 2-phase AC power supply. Never wire it as a single-phase L+N unit; incorrect wiring will cause failure or permanent damage.

5. 배선 순서 (Lockout-Tagout Safety Procedure)
6. Confirm upstream circuit is de-energized and apply lockout-tagout
7. Connect PE protective earth first (reliable earthing is mandatory)
8. Wire the two-phase input lines L1/L2
9. Terminate the 24V DC load cables
10. Inspect for short circuits and earth insulation; confirm no shorted load circuits
11. Apply power and verify the DC OK green LED illuminates; trim the ADJ potentiometer to set target output voltage
12. 수업 2 (C2LPS) wiring rule: Output cabling shall follow NEC Class 2 명세서; no shared trunking with high-voltage power cables without isolation barriers.
13. 보호 기능 & 고장 진단

단락 보호: Constant current limiting. 수업 2 versions feature high sensitivity; short-circuit triggers immediate shutdown, auto-recovery after fault removal.

과부하 보호: Current exceeding 105% rated value activates current limiting

과전압 보호 (OVP): Output shuts down above 35 DC에서

Thermal protection: Over-temperature shutdown; auto-restart after cooling down

저전압 / 위상 손실: No start-up if input voltage drops below 264 뷔와; DC OK light remains off.

7. 환경 & 설치 제한

작동 온도: -25℃ ~ +70℃; 2.5%/K power derating above 55℃

습기: 5%~95% 비응결

Forbidden applications: Outdoor direct mounting, dusty/corrosive atmospheres, water splash exposure

Explosion-proof installation (Class I Div.2 T4): Cabinet-only mounting; external wiring must not create ignition sources, comply with flameproof/enclosure standards.

8. 평행한 & Series Connection

❌ This model does NOT support parallel current expansion or series voltage boosting. Select the QUINT series if multi-unit parallel operation is required.

9. EMC & 접지

The PE terminal must connect securely to cabinet protective earth; floating earth is prohibited

Upstream overcurrent protection recommendation: C-curve MCB, 1 또는 2 에이 (for 400V two-phase circuit)

수업 2 output circuits normally do not require additional fuses; 필요한 경우, implement UL1310 Class 2 current-limiting designs.
