1 GENERAL INFORMATION AND FEATURES 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.
APPLICABLE STANDARDS 2 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 2.3 Protective Classes IEC 529: IPÐ20 VDE 106 Part 1: Class II 2.
3 INSTALLATION AND REMOVAL Warning! 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. For units that must be shipped installed on the rail, additional bracing to resist transportation shocks is recommended.
INSTALLATION AND REMOVAL 3 To 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 3.1 on the following page. 3. On the main board, locate the transformer jumpers W1, W2, and W3 near the transformer T1. Warning! If your power requirement is 115Vac, jumpers W1 and W2 should be installed.
