The compact DRN power supplies are designed to supply well-regulated 21.5 volt DC power to sensors, signal conditioners, data acquisition systems and high level logic equipment.
2.1 Input Voltage Tolerances Exceeds IEC 38 range 2.2 Input / Output Isolation 4KV rms 60Hz 1 minute test 630V conductor spacing, IEC 348 Exceeds VDE551 / IEC 742 separation spacing Exceeds VDE106 protective separation Exceeds VDE 160 clearance distances Exceeds VDE160 creepage distances 2.
The DRN power supplies are heavy enough to cause damage and or injury if dropped during installation. Assure firm rail mounting before releasing grip on the unit. If a rail assembly is to be transported, then disconnection, dismounting and separate packing of the power supply is recommended.
T o change voltage jumpers: 1. Remove cover from case by carefully prying up two side tabs using a screwdriver . Remove two screws from bottom of case. Slide unit out of case. 2. Locate the main board assembly and position it in front of you the same way as shown in Figure 3.
