2. Núcleo Elétrico & Especificações Mecânicas

> ⚠️ Important Distinction: Two models with identical 280×80 outline are easily confused

> W2E250-HL06-01 (230V) ≠ W2E250-HL06-05 (115Versão V). Voltage mixing is forbidden.

3. Estrutura & Características
4. External rotor AC motor: Classic ebm axial fan with metal frame for general industrial cooling;
5. Metal impeller + galvanized steel frame, resistente a vibrações, widely used for forced cabinet ventilation;
6. No built-in thermal protection (external thermostat optional for some batches); sustained power supply under locked rotor condition will burn windings;
7. Avoid frequent full-voltage start-stop operation over long periods. If speed regulation is required, use phase-angle speed controllers. Ordinary voltage regulators are not recommended.
8. Cenários típicos de aplicação

Cooling for frequency converters and high-power servo control cabinets

UPS and industrial uninterruptible power supply cabinets

LV/MV electrical cabinets, air conditioning units and industrial oven ventilation

Cooling for welding equipment and test equipment enclosures

Speed Controller Selection Guide for W2E250-HL06-01 (AC230V, 0.75UM)

⚠️ Critical Note: This fan is a single-phase AC external rotor fan and must be driven by a [Phase-Angle (Tiristor) Speed Controller]; autotransformer regulators and frequency converters are prohibited!

Fan rated current: 0.75UM, select controller with minimum 1.3 times current margin.

1. ebm-papst Original Matching Units (Optimal Compatibility, Superior EMC Performance)

REE Series 230VAC Stepless Phase-Angle Speed Controllers

> Observação: REE10 is the standard original matching model, preferred for overseas & industrial projects; longer lead time and higher cost are disadvantages.

2. Soluções Alternativas (Domestic Industrial Phase-Angle Controllers, Widely Used for Cabinets)

1) Manual Knob Type (Local Adjustment)

Modelos Típicos: ST-1、FS-02、FSC-1A

Requisitos: AC220/230V, continuous current ≥1A, thyristor phase-angle regulation, compatible with single-phase AC axial fans.

2) Automatic Temperature Control Type (Recommended for Constant-Temp Cabinet Cooling)

Equipped with NTC temperature probe to adjust speed automatically according to temperature:

Domestic Models: FSC-T1、JK-1A (230V, 1UM)

3. Prohibited Speed Control Solutions (Armadilhas Comuns)
4. ❌ Frequency Converter: Direct drive of single-phase AC fan will likely burn windings;
5. ❌ Ordinary Autotransformer Regulator: Insufficient low-speed torque and severe overheating;
6. ❌ DC 0–10V Signal Controller: Only applicable to EC fans; incompatible with this AC fan;
7. ❌ AC PWM Chopper Module: Severe harmonic distortion, causing fan noise and vibration.
8. Brief Wiring Instruction (REE10)
9. Entrada de energia: Conecte L, N to 230V mains supply;
10. Saída: Connect to two power leads of the fan;
11. Internal trimmer for minimum startup speed adjustment (to avoid startup failure at low speed);
12. Reliable PE earthing is mandatory.
13. Quick Solution Recommendation

Single fan, equipamento de exportação / high-standard cabinet: Select REE10 directly

Domestic project, controle de custos: Adopt domestic 1A phase-angle fan speed controller; choose variant with temperature probe if automatic temperature regulation is required.
