Switch mechanical properties test power box
A product introduction
POWER - III POWER box, but for vacuum circuit breaker and other high voltage switch to provide operational POWER supply. Two kinds of power box adopts input ac 220 v or 380 v by silicon controlled voltage rectifier, output dc, with output dc voltage shift more adjustable current of the characteristics of big or ac voltage, single points, single joint operation function. And small volume, light weight, easy to carry, particularly applicable to high-voltage switch site commissioning.
Two products main technical parameters
Input power supply voltage exchange:
220 v or 380 v ac
Output dc close, points brake voltage were three files:
I file voltage range: 40-100 v II files voltage range: 38-200 v
III file voltage range: 180-300 v
* note: when the input power of ac 220 v, output maximum of dc voltage 198 v
Flow time:
T < 2 s
Input voltage exchange:
220 v or external voltage regulator input 180-250 v
Output exchange cooperation, point gate voltage:
Ac 220 v or 180-250 v
Output close, points brake current:
5 a
External voltage regulator capacity:
2 kva
