PISA11.CLASS2 Puls Protection Modules (DC)

Out if stock but available for backorder.

PULS PISA11.CLASS2 is a protection unit designed for DIN rail mounting, featuring a 4-channel protection module with 1 input and 4 outputs. It operates within an ambient air temperature range of -25 to +70°C and adheres to NEC Class 2 design standards. The rated current is 16A, distributed as 4A per channel, with a derating to 0.025A/+60°C to +70°C for each channel. It utilizes screw-clamp connections for secure installation and is part of the PISA11-series. The dimensions are W45mm x H75mm x D91mm, and it requires a supply voltage of 18Vdc to 30Vdc, with 24Vdc being typical and 21.4Vdc needed to turn on the outputs. The output voltage is adjustable between 24Vdc and 28Vdc. Protection functions include short-circuit protection with a 10ms shutdown time and current limitation with an adjustable threshold between 16.6A and 23.6A. Power dissipation at full output load with a 24V input is 1.8W, and the processing time for the turn-on delay of output is 270ms. The voltage drop across the unit is 101mV / 0.101 V. Electrical durability is rated at 216,000 hours at 40°C with a 4x2A output and 610,000 hours at 25°C with a 4x2A output.
