Set this on POWER ON STATE menu.
Guide: Menu --- 1. SYSTEM SETTING --- 4. POWER ON STATE --- LAST.
Maximum remote compensation voltage is 5V.
Turn on the current-sharing function to maintain output balance between parallel connected units.
USB, RS485, RS23 and LAN.
Choose SHORT MODE in the menu for cable/circuit breaker testing.
It differs for different types; the minimum is 0.1mV.
3 output modes: AC, DC and AC+DC, 3 voltage stages: 150V, 300V and AUTO.
Choose the Professional Version of APM AC power source, maximum harmonic order is 40.
Built-in IEC standard testing functions are equipped, Advanced Version including IEC61000-4-11; Professional Version including IEC61000-4-11, IEC61000-4-13, IEC61000-4-14 and IEC61000-4-28.
Yes, phase angle is adjustable in range of 0-359.9°, therefore APM AC power source can be started at any phase angle.
Yes, output will be shut down when short circuit occurs, and will be restarted when short circuit issue is removed. However, short-circuiting the AC power source output is not recommended.
By combining three programmable AC power sources, three phase output can be achieved. Phase angle adjusting range of a single unit is 0-359.9°.
Yes, with the interfaces in standard configuration, the programmable AC power source can be connected to external computer for controlling. With free host computer software, tests including scanning, surging, trapping, triac dimming, quick test, etc. can be achieved, data can be recorded and saved conveniently.
When testing AC devices, power meter is necessary for metering voltage, current and power, with built-in power meter, there is no need for connecting external power meter, which is convenient. The APC AC power source is capable of metering 15 electric parameters including voltage, current, frequency, etc., by simply connecting the power source to the DUT.
All versions of APC DC electronic loads are equipped with external analog control interfaces. 0-full-scale controlled with external voltage 0-10V in CC, CV and CR modes.
CC mode of electronic load suitable for constant-voltage mode of power source; CV mode of electronic load suitable for constant-current mode of power source
Over-current, over-power, over-voltage, over-temperature, reverse-alarm, etc. protections.
CV (constant voltage), CC (constant current), CR (constant resistance) and CP (constant power) mode.
RS23, RS485 and USB in standard configuration, GPIB and LAN are optional.
3 operation modes: CC, CR and CP; 4 stop conditions: end voltage, end time, end ampere-hour and end watt-hour; to activate, press On/off button after setting.
Yes, paralleling among DC electronic loads in different voltage stages is supported; up to 20 units can be parallel connected at maximum.
Check if the input cables are correctly connected; check if the initial load voltage is set, set the initial load voltage to 0 or lower than input voltage.
Use hotkey [Shift]+[Range] to simulate short circuit, the short circuit current is the maximum current of the measuring range.
When synchronization is on, load parameters need to be input separately for master and slave, be all slaves’ LOAD ON/OFF actions are synchronized controlled by the master.
