1.        The ripple values are measured at 20MHz of bandwidth by using a 12'' twisted pair-wire termin-ated with 0.1uF & 47uF parallel capacitor under ambient temperature 25°C at rated input voltage and rated load;

2.        The efficiency values are measured under ambient temperature 25°C at rated input voltage and rat-ed load.

  1. This product is built in inrush limiting circuit to protect the circuit from surge current damages when the power is turned on. Malfunction can occur by repeating the input voltage on and off rapidly. Therefore, sufficient interval should be given between turning on and off the power;
  2. To avoid connecting the switch or fuse to input terminal(outside of the power supply), more consideration should be given when selecting the parts that can endure the inrush current

Output voltage adjustment range

Output voltage can be adjusted within above range by V-ADJ. variable resistance inside of the power supply. When output voltage exceeds the range, the power supply will be in failure or get into over voltage protection mode. To avoid the case that the output voltage is higher than rated voltage, output current should be used under rated current

PROTECTION

Short circuit

Hiccup mode, it will recover automatically after fault condition is removed

Over voltage

RIRA15-12: over voltage protection value 18V 

RIRA15-24: over voltage protection value 30V

  1. When output voltage exceeds above over voltage protection value or reversal voltage occurs, the protection will be started and the output voltage will be cut off in order to protect the power supply;
  2. The power supply will recover after the power is turned on again

Over current

RIRA15-12: over current protection value 1.8A 

RIRA15-24: over current protection value 0.9A

  1.  When output voltage exceeds above over current protection value, the protection will be started and the output voltage will be cut off in order to protect the power supply;
  2.  The power supply will recover automatically after the fault condition is removed

Over temperature

Over temperature protection value: 100±10°C

  1. When the ambient temperature exceeds above over temperature protection value, the protection will be started and the output voltage will be cut off in order to protect the power supply;
  2. The power supply will recover after the power is turned on again
