NOTES

1. Depends upon specific model selection, output voltage, and/or upon 120 or 240 VAC operation.
2. Products are rated for industrial environments and are not to be used nor are warranted in aerospace, medical or life-safety applications.

NOTES

1. DEPTH excludes the 0.3125” (9mm) DIN Rail mounting bracket.
2. WEIGHT is ‘net’, excluding packaging/shipping.
3. Recommended clearances at higher ambient operating temperatures for proper airflow and heat dissipation: 25mm sides, 70mm top/bottom

NOTES

1. TERMINALS – Two positive “+” and two negative “–” DC output terminals on the unit, are respectively connected in parallel inside the unit.
   They actually belong to the same output pole. It is recommended that both “+” and both “–” output terminals be connected to the load.
2. PARALLEL OPERATION TO INCREASE OUTPUT POWER The same models must be used and the output voltages of all units must be set to the same value.
   The load connection wires are recommended to be of the same gauge and length.  Add an isolating diode or DC fuse at the positive outputs of each of the units.
   Check all earth leakage currents.
3. PARALLEL OPERATION FOR REDUNDANCY APPLICATION To increase reliability of system, two units of the same model may be used for redundancy operation.
   In normal operation, each unit supplies 50% of load current. When a failure occurs on unit 1, then unit 2 immediately and automatically overrides
   unit 1 to continue the operation and supply 100% of the load current. All load connection wires should the same gauge and length and unit output voltages
   must be set as close as possible to the same value. Add a fuse or decoupling diode at the positive outputs of the two units.  Check all earth leakage currents.
4. “DC OK” LED INDICATOR  The indicator lights up indicating the unit operate is operating normally. 
   The indicator flashes indicating the output voltage is over normal value or a load short circuit, overload or overheat condition exists.
   The indicator turns off indicating a power failure or there is no AC input.
5. ACTIVE “DC OK” OUTPUT SIGNAL TERMINAL This is similar to the “DC OK” LED that indicates the operating status of the unit.
   Users may connect an external indicator or the equivalent (40mA) between the terminals for remote monitor.
