Response Time

CHITEK AHF features a full response time of less than 50 microseconds (<50μs), enabling real-time harmonic compensation that responds instantly to dynamic load changes.

This ultra-fast response ensures that even rapidly fluctuating loads such as welding machines, elevators, and variable frequency drives are effectively compensated without delay, preventing harmonic buildup that could damage sensitive equipment.

Parallel Operation

Yes, CHITEK AHF units are designed for parallel operation. Up to 10 units can be paralleled without any communication cables, using a proprietary master-slave control algorithm.

Key benefits of parallel operation:

• Capacity expansion from 30A to 3000A+
• N+1 redundancy for critical applications
• Automatic load sharing with droop control
• Hot-swappable modules for maintenance without downtime

Parallel systems can be configured in less than 5 minutes through the intuitive front panel interface.

Communication Protocols

CHITEK AHF supports the following communication protocols for remote monitoring and control:

• RS485 / Modbus RTU — قياسي في جميع الطرازات
• Ethernet / Modbus TCP — optional interface module
• Profibus DP — optional for industrial automation integration
• Dry contact I/O — for simple start/stop and alarm signaling

جميع معلمات الاتصال (معدل البت، التكافؤ، عنوان العبد) قابلة للتكوين عبر لوحة المفاتيح وشاشة الواجهة الأمامية. توفر تشيتكتك أيضاً برنامج مراقبة مجاني يعمل على الكمبيوتر لتسجيل البيانات وتحليل الاتجاهات.

Lifespan and Maintenance

CHITEK AHF has a design life exceeding 15 years under normal operating conditions (ambient below 40°C, nominal load). Regular preventive maintenance is recommended every 12 months to ensure optimal performance.

• DC bus capacitor replacement: every 8-10 years (recommended)
• Cooling fan replacement: every 5-7 years (based on operating hours)
• Air filter cleaning: every 3-6 months (dusty environments)
• Firmware updates: available via CHITEK PC software tool

جميع منتجات AHF من تشيتكتك تأتي بضمان قياسي لمدة سنتين، مع خيارات ضمان ممتدة تصل إلى 5 سنوات.

Transformer Requirements

No, the CHITEK AHF does not require a dedicated isolation transformer. It connects directly to the low-voltage bus (380V-480V, 50/60Hz) through the existing circuit breaker or fused disconnect.

However, proper current transformer (CT) installation is critical for correct operation:

• CTs must be installed on the mains side (grid source) of the load
• CT ratio should be selected so the secondary current is 1A or 5A at full load
• CT accuracy class 0.5 or better recommended for optimal performance
• مسافة توصيل CT قياسية تصل إلى 100 متر مع حماية مناسبة

Harsh Environment Operation

CHITEK AHF is designed for reliable operation in demanding industrial environments:

• Operating temperature: 0°C to +50°C (standard), with automatic derating above 40°C
• Storage temperature: -25°C to +70°C
• Humidity: 0-95% non-condensing
• حماية الدخول: IP20 قياسي، IP31 اختياري (المعادل NEMA 1)
• Altitude: up to 2000m without derating, up to 4000m with derating

For extreme environments (high dust, corrosive gases, outdoor), CHITEK offers custom enclosure options including forced ventilation, heat exchangers, and stainless steel construction.

Certifications and Compliance

Custom certification packages are available for specific regional or project requirements.

Commissioning and Configuration

تم تصميم AHF من تشيتكتك للتشغيل السريع والبديهي. تستغرق عملية الإعداد القياسية أقل من 15 دقيقة وتنطوي على ثلاث خطوات بسيطة:

1. Auto-tuning: The AHF automatically detects line impedance and CT configuration with the press of a button
2. Harmonic selection: Choose from pre-configured harmonic profiles or customize individual harmonic orders (2nd-50th)
3. التحقق: عرض الموجات المدمج وحلل طيف التوافقيات يؤكدان التشغيل الصحيح

For advanced configurations, CHITEK provides a free PC-based software tool for parameter backup/restore, data logging, and remote monitoring setup. Multi-unit parallel systems can be configured in under 5 minutes through the intuitive front panel interface without any external tools.
