• BLD Series Signal light

  BLD series indicators are all using high bright solid color LED light chip as the light source, long life, low energy consumption, small size, light weight, is XD all kinds of white woven lights and neon lamp replacement products. The products have passed the CCC mandatory product certification of CQC Center, the CE safety certification of the European Community and the type approval of Marine products of China Classification Society.

  Product Introduction:

  BLD series of indicators in the door engine indicator light is Bruder electric specifically developed for the locomotive industry, play the role of opening and closing instructions. Products with high height
  Bright LED as light source. With the characteristics of high brightness, long life and good shock resistance, the product has two specifications to choose from.

  Conditions of Use:

    ◾  1, ambient temperature :-40℃~+85℃
    ◾  2, air relative humidity ≤98%;
    ◾  3, anti-vibration: 10-2000 H2·1mm·15g
    ◾  4, installation limit height ≤2000m
    ◾  5, in line with EMC directives, that is, electromagnetic compatibility
    ◾  6, installation category: Class III
    ◾ 7, pollution level: 3
    ◾ 8, flame retardant grade: Ⅴ-0
    ◾ 9. Protection grade: exposed part IP67

  Main technical indicators:

  Rated insulation voltage: 400V
  Power frequency voltage: 2.5kV(test voltage is AC RMS value)
  High brightness: ≥150mcd
  Continuous working life: ≥100000h
  Insulation resistance: ≥2M
  Brightness: > 75mcd
  Compared to leakage marking index: CTI≥100
  Allowable voltage fluctuation: voltage ≤48V, allowable fluctuation soil 5%; Voltage > 48V, 20% fluctuation soil allowed

  Note:

  1. At present, the company Ø22 and corresponding ultra-short products can withstand the induction voltage of 20% of the operating voltage.
  2, resistance to more than 20% of the induced voltage of the lamp cost is 3-5 yuan higher than similar lights, and all need to be customized, the production cycle is three working days

  3, in the flash circuit, the working current should be more than 8mA, the anti-interference threshold can not be too large, otherwise the signal light may not work.

  4, by optimizing the voltage reduction scheme, ultra-short signal lamp can be used for DC220V and above voltage.
  Product Size:

  
• 1. Voltage: DC70-140V
  2, light source: ultra-bright LED
  3, light shell color: red, yellow
  4, wiring method: the external lead of the product is 0.75~1.2mm2 rigid wire (insert it)
  5, Product application: Shanghai Metro Line 1, Line 9, Line 11, Chengdu Metro Line 1, Beijing Metro Line 10
