1 Low voltage input and high slew rate electronic load Available for low voltage and high current High slew rate with 100A/μs Low voltage input and high slew rate electronic load Kenwood TMI Corporation changed the corporate name to Texio Corporation on Dec. 1, TEXIO CORPORATION

2 PXL-151A is an Electronic Load with low voltage input and high slew rate. Outline can be run with minimum operating voltage 0.3V. Slew rate is high speed response such as max. 100A/μs with approx. 4V input and 50A/μs with even approx. 2V input. Equipped with each discharging mode, constant current(cc), constant resistance(cr), constant power(cp), and constant voltage(cv). Those settings and confirmation of setting conditions can be made easily with LCD panel and joystick operation. For external control, GP-IB, USB, and RS-232C interfaces are equipped as standard, and all settings and operations can be performed through computer. It can be used widely in evaluation and testing for micro processor POL and VRM power supplies, other electronic power supply circuits, batteries including fuel cells, electronic components, etc. Features Low voltage operation of 0.3V/ 2 can be run with above min. operation voltage 0.3V Limit by power Input voltage(v) Relations between input voltage / input current ( ) Slew rate setting When keenly changing current such as switching operation, slew rate can be set finely. Slew rate can be set separately for each rising and falling x 160 dot graphic LCD panel Plural number of information such as setting conditions, monitoring values, etc can be displayed on 240 dot x 160 dot graphic LCD panel. Also using joystick and rotary encoder on the front panel, value and mode settings can be made while confirming the LCD panel information. 6 point preset memories Incorporated six preset memories ( PRESET A to F) can memorize different setting values for each discharging mode and range. Preset A, B, and C are located on the front panel for easy readout of each setting value. (Preset D,E, and F are read out with menu display.) External Interface External interfaces, such as GP-IB, USB, and RS-232C are equipped as standard. All setting and monitoring measurement values can be controlled by computer. Various monitoring signals There are trigger signal output which outputs synchronized pulse in switching operation, current monitor which outputs converted voltage level (0V to 1.5V) from input current, and voltage monitor which outputs converted 0V to 3V from input voltage. 1:At internal voltage sensing point 2:At static operation 3:Separate setting is not possible when using external voltage control. Slew rate setting for voltage change in CV discharging mode is not possible. Factory option Low voltage input and high slew rate electronic load PXL-151A Two functions can be added as factory option(installation together with both options is possible. ) 1. Sequence function option Setting for max. 1,024 steps by 10μ s step is possible. 2. Simple logger function option It records loading data. Max. logging time is 72 hours 49 minutes by one cycle/sec (in case of one item ) *Logging time will change by number of logging items.

3 Setting value Available for low voltage and high current High slew rate with 100A/μs Functions Superimposing function Current value corresponded to external input AC voltage can be added (superimposed) to the setting DC current value in constant current (CC) discharging mode. External control Key lock function Control keys on front panel can be locked to avoid mistaken change of setting value or misoperations. Short function Setting value (Dotted line) Setting value can be changed to rating current of the current range at once in CC discharging mode. Setting value can be changed to min. resistance value at once in CR discharging mode. Setting with external voltage(0v to 10V) is possible in all discharging modes *4. Wide frequency characteristics of internal control circuit are 200kHz at 0-10V operation and 1MHz(-3dB) at 2V(p-p).( Actual frequency characteristics of current will change with conditions of power source and wiring.) Also load on/off by external contact is possible. Rated setting value Minimum setting value 0 Soft start function(cc discharging mode only) 10Input voltage(v) Power source output may have distortion due to current rising time of the load effected by output on/off of the power source when loading on. By using soft start function which can set rising time and expecting input voltage for starting current, distortion can be minimized, and much closer test similar to actual load can be made. Current Input voltage Input current Current Current 0 0 Soft start function off Current value corresponding to AC voltage from external input (Solid line) Set operating voltage Input voltage Input current Setting time Soft start function on Switching function Switching operation which changes PRESET A and B alternatively is possible. There are two kinds of methods for setting, which are made by switching frequency(1hz to 50kHz*5) and duty ratio(1% to 99%), and the other by each time for A and B. -related function Elapsed time (from load on to load off) display function, automatic load on timer function to set time for automatic loading start.,and automatic load off timer function to set time for automatic loading off. Remarks: It is not possible to use on timer and off timer at the same time. Failsafe function Intending to safety, variety of protection functions and alarm functions are equipped. Protection function Over current protection(ocp)/over current limit(ocl) When inputted current exceeds set current, it loads off(ocp) or keeps the value(ocl) Over power protection (OPP) / Over power limit (OPL) When inputted power exceeds set power, it loads off (OPP) or keeps the value (OPL). Under voltage protection (UVP) When inputting lower voltage than set value, it loads off. Alarm functions Over voltage alarm (OVA) When inputted approx. 115% of max. input voltage, it loads off. Over current alarm (OCA) When inputted approx. 115% of max. input current, it loads off. Reverse voltage alarm (REVA) *6 When added reverse voltage ( approx.-0.4v) to input terminal, it loads off. Over heat alarm (OHA) When internal heat sink temperature becomes more than 110, it loads off. External alarm (EXTA) PRESET A PRESET B DUTY(%) (A/μs) (A/μs) When inputted alarm signal from outside, it loads off. FREQ(Hz) *4. It can not be set below 0.8V in CV discharging mode. *5. Frequency setting range in CV discharging mode is up to 1kHz. *6. This is alarm function and not to protect the unit.
