It delivers a 170 V AC three-phase output at 11 A, controlled via sine-wave PWM and a current control method. The interface power supply is 24 V DC ± 10% drawing 0.3 A. ## Built-in dynamic brake and network cycle A built-in dynamic brake handles deceleration without an external resistor for most load profiles. The SSCNET III/H communication cycle can be set to 0.444 ms or 0.888 ms, matching the high-speed synchronous motion bus common in Mitsubishi setups. The amplifier is force-cooled with an IP20 open enclosure, suitable for cabinet mounting.","metaTitle":"Mitsubishi MR-JE-300B Servo Amp, 200 V AC, 14 A","metaDescription":"Mitsubishi MR-JE-300B servo amplifier, active production. 200 V AC input, 24 V DC supply, 14 A.
