✅ التطبيقات النموذجية

Control cabinets with 400V two-phase power supply, hazardous locations, آلات البناء, التدفئة والتهوية وتكييف الهواء, wind turbine auxiliary control systems; power supply for PLCs, مفاتيح القرب, solenoid valves and HMIs.

تمييز مهم: 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.

✅ دليل استكشاف الأخطاء وإصلاحها

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

2. متطلبات التخليص (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 (المقاولين, braking resistors); high ambient temperature will trigger power derating

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

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

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

4. مواصفات الأسلاك (M3 Screw Terminals)

نوع المحطة: Screw clamping terminals

حجم الموصل: Solid wire 0.2–2.5 mm²; stranded wire 0.2–2.5 mm²; AWG24～AWG14

Strip length: 8 مم

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

تشديد عزم الدوران: 0.5–0.7 Nm (avoid over-tightening to prevent thread damage)

تعريف المحطة (شديد الأهمية: Two-phase input, no neutral N!)

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

محطات الإخراج: +24 V, 0 V (24 في العاصمة)

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

مؤشر: 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. Wiring Sequence (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. فصل 2 (C2LPS) wiring rule: Output cabling shall follow NEC Class 2 تحديد; no shared trunking with high-voltage power cables without isolation barriers.
13. وظائف الحماية & تشخيص الخطأ

حماية ماس كهربائى: Constant current limiting. فصل 2 versions feature high sensitivity; short-circuit triggers immediate shutdown, auto-recovery after fault removal.

حماية الزائد: Current exceeding 105% rated value activates current limiting

حماية الجهد الزائد (نائب الرئيس): Output shuts down above 35 في العاصمة

Thermal protection: Over-temperature shutdown; إعادة التشغيل التلقائي بعد التبريد

انخفاض الجهد / خسارة المرحلة: No start-up if input voltage drops below 264 الخامس و; DC OK light remains off.

رطوبة: 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. موازي & 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. إي إم سي & Earthing

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

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

فصل 2 output circuits normally do not require additional fuses; إذا لزم الأمر, implement UL1310 Class 2 current-limiting designs.
