✅ Типичные применения

Control cabinets with 400V two-phase power supply, hazardous locations, строительная техника, ОВК, wind turbine auxiliary control systems; power supply for PLCs, бесконтактные переключатели, solenoid valves and HMIs.

Важное различие: 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.

✅ Руководство по устранению неполадок

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

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

Vertical stacking: Минимум 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 (контакторы, braking resistors); high ambient temperature will trigger power derating

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

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

Устойчивость к вибрации: Compliant with industrial cabinet vibration standards; no extra locking screws required once clipped firmly.

Strip length: 8 мм

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

Момент затяжки: 0.5–0.7 Nm (избегайте чрезмерной затяжки, чтобы предотвратить повреждение резьбы)

Определение терминала (Критический: Two-phase input, no neutral N!)

Output terminals: +24 В, 0 В (24 В Вашингтоне)

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

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

⚠️ Критическое предупреждение: 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. Последовательность подключения (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
