✅ Aplicaciones típicas

Control cabinets with 400V two-phase power supply, hazardous locations, maquinaria de construcción, climatización, wind turbine auxiliary control systems; power supply for PLCs, interruptores de proximidad, solenoid valves and HMIs.

Distinción importante: 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.

✅ Troubleshooting Guide

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

FÉNIX 2904371 (UNO-PS/2AC/24DC/90W/C2LPS) Manual de instalación

1. Descripción general del producto

Nro. de orden: 2904371

Serie: UNO POWER 2-phase DIN rail power supply

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

Producción: 24 En DC, 3.75 A / 90 W., adjustable 24–28 V

Montaje: NS35 DIN rail (EN60715), instalación horizontal

Ancho de la carcasa: 55 milímetros

2. Requisitos de autorización (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 (contactores, braking resistors); high ambient temperature will trigger power derating

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

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

Resistencia a las vibraciones: Compliant with industrial cabinet vibration standards; no extra locking screws required once clipped firmly.

4. Especificaciones de cableado (M3 Screw Terminals)

Tipo de terminal: Screw clamping terminals

Tamaño del conductor: Solid wire 0.2–2.5 mm²; stranded wire 0.2–2.5 mm²; AWG24～AWG14

Strip length: 8 milímetros

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

Par de apriete: 0.5–0.7 Nm (Evite apretar demasiado para evitar daños en la rosca.)

Definición de terminal (Crítico: Two-phase input, no neutral N!)

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

Terminales de salida: +24 V, 0 V (24 En DC)

Adjustment potentiometer: ADJ (24~28 V fine-tuning; factory preset to 24 V)

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

⚠️ Advertencia crítica: 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. Secuencia de cableado (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. Clase 2 (C2LPS) wiring rule: Output cabling shall follow NEC Class 2 presupuesto; no shared trunking with high-voltage power cables without isolation barriers.
13. Funciones de protección & Diagnóstico de fallas

Protección contra cortocircuitos: Constant current limiting. Clase 2 versions feature high sensitivity; short-circuit triggers immediate shutdown, auto-recovery after fault removal.

Protección contra sobrecarga: Current exceeding 105% rated value activates current limiting

Protección contra sobretensión (OVP): Output shuts down above 35 En DC

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

Subtensión / pérdida de fase: No start-up if input voltage drops below 264 V y; DC OK light remains off.

7. Ambiental & Installation Restrictions

Temperatura de funcionamiento: -25℃ ~ +70℃; 2.5%/K power derating above 55℃

Humedad: 5%~95% non-condensing

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. Paralelo & 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. CEM & Toma de tierra

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

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

Clase 2 output circuits normally do not require additional fuses; si es necesario, implement UL1310 Class 2 current-limiting designs.
