| | | EFS8326/27 | | |
| | | |
| | | The EFS 8326 and EFS 8327 power supplies manufacturer are current sources delivering a sinusoidal output isolated from the network at a frequency of 50Hz or 60Hz, adjustable either from 0 to 170 A (EFS 8326), or from 0 to 1300 A (EFS 8327). Each power supply is adjustable within 5 ranges: EFS8326 : 0.8 A / 2.5 A/18 A/60 A/170 A EFS8327 : 40 A/125 A/250 A/650 A/1300 A | | |

| | | APPLICATIONS | | |
| | | |
| | | Used for testing devices with thermal, magnetothermal and magnetic triggering systems such as relays, circuit breakers or bimetallic strip industrial thermometers. | | |
| | | |
| | | USE | | |
| | | |
| | | The EFS 8326 or EFS 8327 power supplies are each housed in a cabinet (800x1200x1600). The control panel, situated on the front door, is equipped with an emergency punch-stop button enabling activation of the isolation command. The operator is equipped with a keyboard used for choosing the functioning mode (local, external, bus) and the range as well as for frequency and cycle management. A potentiometer allows parameter adjustment. 3 displays provide the user with essential information: «duration or 1/2 period*, «current» and «output voltage». | | |

| | | MAIN FUNCTIONS | | |
| | | |
| | | z m < | | |
| | | • displays precise measurements of the current and the output voltage. | | |
| | | |
| | | • carries out complete test cycles (beats, ramps,time slots... ) with a resolution | | ai • 1 | | |
| | | |
| | | |
| | | of 1/2 a period (duration of the control system loop). • user protection provided by numerous safety features (insulation, emergency stops) but also power supply protection (overloads). - either via isolated On-Off inputs and outputs and an analog input - or by a MODBUS link. | | |
