Parallel operation
|
|
Master-Slave operation. One
master unit can control up to 4 units of slaves of same
voltage rating. For example: If the master unit is ELA-305
then ELA-155, ELA-305 or ELA-1005 may be connected as slave
unit. |

*1 : Nominal resolution:
Approximated resolution of the range.
*2 : Conv.Curr: Ideal current value being calculated by [input / set
R]
*3 : Min load response time: Minimum time required by the load when
setting slew rate.
*4 : Rin: ELA-155 : 100kohm(typ) ELB-155 : 200kohm(typ) ELC-155 :
1500kohm(typ)
*5 : External control setting accuracy: Setting accuracy is defined
when external control
voltage of 10V is fed.
*6 Setting accuracy in CR mode is valid when applied 10% or more
voltage of the voltage range.
*7 : It may vary in accordance to the internal temperature.
*8 Minimum operating voltage vary according to the current value.
*9 At rear loading terminals.
