Construction Drawing of Pulse Resistor SUR:
Performance Test of Pulse Resistor SUR:
1.Installation: Horizontal direction;
2.Acceleration: 490m/s²
3.Times of pulse characetic: 11ms
4.Pulse shape: Halfsinusoid;
5.Calculation of charge and dischargetest Voltage:E=
,Among them: E=Test voltang(V) ,P=Test power of theresistor(W),R=Testresistance( Ω) , N=Multiples of the pulse power.
6. Energy storage capacitance: C=T/R*10³ T=11ms
7. Temperature rise chart which shou the multiples of the over pawerof the resistor elements and the time constant.
8. Visually Inspection: Logo clearly no damage to the packaging.
9. Inspection of the resistance: Δ=±(1 %+0.05Ω )；
