JS-11A SERIES Adjustable TIME Electronic Control Relay (JS-11A/331)
JS-11A series IC time relay adopt quartz oscillator and CMOS special IC, its precision lots of hither than electornaenetism type and RC type time relay. It quarantee time grade for main protection and reserue protection in electric power system. It is the best substitution of the old time relay.The series relay is the same with DS electromagnetism time relay in figure, inner commection and working, and setting value range is more wide, grade more snall, and setting more straight. In yts range 0.02S-999H, it can set randomly and guarantee precision without adjusting. Making the operate time time of parts controled adjustable, used in kinds of protection and auto circuit.
Main tech-parameters
1 Delay range and grade delay range: 0.02S~999M.
grade:0.01S. P type:0.1S~30S.
2 Delay setting error Temperature 20℃±5℃, under rated
voltage, Delay setting error of relay(involving
consistency):setting value≤100S, error<+0.1S;setting value>100S,
error<±0.1%.
3 resetting time less than 20mS.
4 permit voltage fluctuating range permit voltage
fluctuating range is 0.8~1.1 times of ratedvoltage.
5 Contact capacity: Relay output circuit contact can
break the voltage less than 250V, 80W for the DC inductance charge
circuit which time constant is 5±0.75ms. In the AC circuit which
voltage is less than 250V it is 300VA(power factor cosΦ is
0.4±0.1). Relay’s contact can make 10A for long life.
6 Enviroment temperature -10℃~+50℃
7 Medium intensity: Relay’s every electric terminals
are connected together. And it can endure a 2000V and 50Hz AC
voltage(virtual value) to the non-electrification metallic outside
part or shell. There is no insulated breakdown or flashover
phenomenon.
8 Insulation resistance: Relay’s every electric
terminals are connected together. To the non-electrification
metallic outside part or shell, its insulated resistance is less
than 300MΩ measured by tramegger with opening voltage is
500V.
9 Electrical endurance Above 105 times.
10 Mechanical endurance Above 106 times.
11 Power consumption: Less than 5W under rating voltage
condition.
12 Anti-disturb capability Relay’s anti-disturb is
accord with DL478-92 ()
