1: Machine operates with 0V input. However in order to let current flow in equivalent to setting resistance, 1V or more should be input. 2: Machine operates with 1V input or less. However the current actually flows in is less than setting current value or calculated value from input voltage and setting value. In CV mode, affected by current., actual voltage should be more than setting value.

Maximum power will be affected by setting current range. Only rating current of setting current range will be loaded when voltage is set to 1V or more. Input current fluctuation: fluctuation for current at input voltage is 1V and 10% to 100% of rating value (when remote sensing is operating) Each Setting range and other setting for CV+CC and CV+CR is equivalent to the CC mode and CR x 1 mode. Noted that CV+CR x 10 mode is NOT available. LSA series has 3 current ranges. So that 6 type of range will be available for each CV+CC and CV+CR.

Features
LSA series is an electronic load which has full-color 3.5 inch LCD display. It provides high operability and visibility. 3 types are available – LSA-165: Input power is 165W (150V/33A), LSA-330: Input power is 330W (150V/66A), LSA-1000: Input power is 1000W (150V/200A). External control interface is standard equipped. GP-IB, USB and RS-232C option control board IF-80GUR provides extended digital interface. Maximum 5-unit-parallel master-slave operation is available.

●　Compact size which is 1/3-rack-size for 165W model and 330W model. Reduce the bulk ratio to 60% of that of the conventional company products.
●　Full-color 3.5 inch LCD provides high operability and visibility.
●　10μA minimum resolution for current setting (LSA-165 L range).
●　Constant Current(CC), Constant Resistance(CR), Constant Power(CP), Constant voltage(CC+CV/CR+CV) mode are selectable.
●　High-speed response for 10μsec. Switching function is available (CC, CR, CP mode).
●　Setting voltage and resistance can be controlled via externally.
●　Maximum 5-unit-parallel master-slave operation is available.
●　Sequence control provides branch on condition.
●　Option: GP-IB, USB and RS-232C are in one slot-in option board IF-80GUR.
* Recommend to use GP-IB or RS-232C if you use LSA seriese at noisy condition
