General Notes:
  • When used in Cover Kit, derate output power to 70% under all operating conditions
  • Output ripple can be more than 2 % of the output voltage at low load condition
  • All specifications are measured at nominal input voltage, 25°C, unless otherwise specified
  • MEPG300-13XX-G series is with specific connector & Mounting Hole Provision, refer mechanical specification. (Contact Sales for more details)
Notes:
  1. Ripple is peak to peak with 20 MHz bandwidth and 10 μF (Electrolytic capacitor) in parallel with a 0.1 μF capacitor at rated line voltage and load ranges
  2. Refer Derating Curves
  3. Output ripple can be more than 10 % of the output voltage
