The Model A1513B is a single width (5 TE wide) board housing 6 LV floating channels. The output voltage range is 0÷10 V (2.7 A maximum output current) with 10 mV monitor resolution.
The board is provided with Remote Sensing Lines to compensate for the voltage drop over the connection cables.
If the output voltage differs from the programmed value by more than 3% of voltage full scale range, the channel is signalled to be either in OVERVOLTAGE or UNDERVOLTAGE condition. Moreover, for each channel, a voltage protection limit SVMAX can be fixed via software with 0.1 V resolution and the output voltage can not be programmed beyond this value.
The LV RAMP-UP and RAMP-DOWN rates may be selected independently for each channel in the range 1-19 V/s in 1 V/s steps.
The output current is monitored with 10 mA resolution; if a channel tries to draw a current larger than its programmed limit it is signalled to be in OVERCURRENT condition; the SY1527 system detects this state as a fault and reacts according to the setting of the TRIP parameter, namely:
1) TRIP=infinite ( = 1000 s)
When the maximum output current value is reached the channel behaves like a constant current generator.
2) TRIP=finite (< 1000 s)
The output current is permitted to exceed the limit only for programmed time interval and then is switched off.
The TRIP time (i.e. the maximum time an OVERCURRENT condition is allowed to last) can be programmed in 0.1 s steps.
The maximum output voltage (VMAX Hardware) can be fixed, through a potentiometer located on the front panel, at the same common value for all the board channels and this value can be read out via software.
The boards are provided with an "EN" input that disables the channels when it is not connected to ground
