TR-668R Electronic
load tester
|
| |
| |
|
|
|
 Characteristic： |
| |
 4 of 300W
module unit：60V、60A、300W ×4 |
| The module
from various places can be carried out alone: the stable electric
current; |
| ___the stable voltage, the stable
resistance, the stable power mode; |
| 4 load
module unit can connect by sereis/parallel |
| 4 module
the operate function like TR-668; |
|
Take one GPIB address only , can remote control all (options) |
