Chint ND2 series audible and visual alarm lights

Chint ND2 series audible and visual alarm lights are industrial devices that integrate sound and light warning functions, suitable for safety prompt needs in various scenarios. The following is a summary of their core information:

1. Technical Parameters and Functional Characteristics
2. Electrical تحديدChint AC Contactor

It supports three voltage inputs: DC12V, DC24V and AC220V (50هرتز), which can be adapted to different power supply environments. على سبيل المثال, the ND2-51ZFB/DC12V model uses 12V DC power supply, which is suitable for vehicle-mounted or low-voltage equipment.

2. Acoustic and Light ModesCHINT Contactor NC1-09

Light-emitting modes: There are three forms: constant light (ج), rotating strobe (ز), and strobe (س). The colors include red, yellow, green, and blue. Different combinations can be selected according to scene requirements (على سبيل المثال, red strobe is used for high-risk warnings).

Sound forms: Divided into buzzer (ف) and silent models. The loudness of the buzzer is not clearly marked, but user feedback indicates that its response is rapid and clear.

3. القدرة على التكيف البيئيSchneider-MCCB-NSX250F-4P-250A

Temperature range: The operating temperature is -5℃~+40℃, and the extreme temperature can reach -25℃~+55℃, مناسبة للبيئات الصناعية القاسية.

Protection level: Some models (such as those with buzzers) have a protection level of IP45, which is dust-proof and splash-proof; silent models have IP20, suitable for dry environments.

2. Industrial FieldSchneider Circuit Breakers Price

Widely used in factory workshops, lathe equipment, construction site sentry boxes and other places as warning signal sources for equipment failures, abnormal operation or safety accidents. على سبيل المثال, in the gas leakage monitoring device of the reactor, ND2 serves as an alarm flashing light, which triggers an audible and visual alarm in linkage with the gas concentration sensor.

2. Public Security

ND2 is used in security systems to achieve comprehensive early warning in conjunction with face recognition, turnstiles and other equipment.

3. General Warnings

Suitable for scenarios requiring sound and light prompts, such as warehouses, parking lots, laboratories, إلخ. Specific information is transmitted through combinations of different colors and modes (على سبيل المثال, green constant light indicates normal operation, red strobe indicates emergency situations).

ثالثا. Model and Selection Suggestions

1. Model Coding Rules

ND2 models are composed of letters and numbers. على سبيل المثال, ND2-51ZFR/AC220V:

First letter: ج (constant light), ز (rotating strobe), س (strobe);

Second letter: ف (buzzer) or empty (silent);

Third letter: ر (red), Y (yellow), G (green), ب (blue);

لاحقة: voltage specification (على سبيل المثال, تيار متردد 220 فولت).

2. Typical Model Examples

ND2-51SFR/AC220V: Red strobe + buzzer, 220V AC power supply, suitable for warning of factory power equipment.

ND2-51ZFB/DC24V: Blue rotating strobe + buzzer, 24V DC power supply, suitable for mobile equipment in automated production lines.

1. Purchase and Certification
2. Market Supply

International Market: Chint has sales networks in North America, Europe and other regions, but for ND2 export, please contact via Whatsapp: 0086-13811255435.

2. Certification Information

شهادة المحلية: Complies with China’s national standard GB/T 14048.5 and has passed CCC certification.

International Compatibility: Some Chint products have passed UL and CE certifications, but the specific international certification information of the ND2 series is not clearly mentioned. It is recommended to confirm with the manufacturer before purchasing.

1. User Feedback and Installation Suggestions
2. Usage Experience

Advantages: Users evaluate it as easy to wire, strong durability, with complete accessories, convenient installation, fast response speed, and effective prevention of accidents.

Matters Needing Attention: The buzzer model may need to be combined with the light mode to enhance the warning effect in high-noise environments. It is recommended to choose the sound and light combination according to the actual scenario.

2. طرق التثبيت

– Supports rail installation or magnetic fixation (some models come with mounting brackets), which can be flexibly adapted to different equipment surfaces.VI. النماذج البديلة ومعلومات التوقف

Atesent, the search results do not clearly mention the discontinuation of the ND2 series, but there are model iterations in other Chint product lines (such as circuit breakers) (على سبيل المثال, DZ267LE is upgraded to NXBLE). For long-term procurement, it is recommended to confirm the market status of ND2 and the subsequent replacement plan with the manufacturer.

ملخص

Chint ND2 audible and visual alarm lights have become the mainstream choice for industrial safety warnings due to their multi-voltage compatibility, rich sound and light modes, and reliable environmental adaptability. Users can choose appropriate models according to specific scenario requirements (such as voltage, protection level, color mode) and purchase through regular channels to ensure product quality. For users in the international market, it is necessary to further verify product certification and local adaptability.
