energy supply
521 50
AC/DC power supply 0 ... 15 V/ 5 A
High-performance power supply which can
also be used as a constant-current source. AC
voltage is electrically isolated from the DC voltage
and can be adjusted in seven steps from
2 to 15 V/5 A. Overload protection via overcurrent
circuit breakers; capable of supporting full
load while simultaneously supplying DC. Stabilized
and regulated DC voltage continuously
adjustable, 0...15 V, 0...5 A. With two 2 1 / 2 -digit
displays for current and voltage; permanent
electronic short-circuit protection and protection
against interference voltages. Separate
LED indicators for constant current and constant
voltage operation.
Output voltages:
2, 4, 6, 8, 10, 12, 15 V AC
