Full performance within the range of 355 VAC (L-L) to 485 VAC (L-L), 44Hz to 77 Hz. Input surge: up to 594 VAC for 2 sec. No damage for any voltage between 0 to the above limits. Power Factor >0.98 at full load and 50/60Hz. Spikes Withstand 2,500 V spikes IAW MIL-STD-1399-300B. Inrush Current Internally limited such that the peak RMS current is less than 15Arms and recovers to below 6Arms within 50mS. Isolation Input is galvanically isolated from output and chassis (> 20 MΩ at 1,500 VDC). Capacitance between AC input to chassis is less than 0.1µF per line (MIL-STD-1399 compliant). Less than 1mA low-frequency and less than 14mA high-frequency human body leakage (less than 1/5 of the maximum allowed by MIL-STD-1399-300B, allowing safe parallel connection of up to five M9204 units). Current Waveform Low-distortion Sinusoidal, complies with the Harmonic Current limits of MIL-STD-1399-300B. Missing Phase Protection Protected from missing phase. Automatic recovery upon phase restoration. DC Output Rating 3.2 kW, models with nominal output voltage of up to 80VDC and rated current up 110Amp are available (see the Standard Models on Page 1). Voltage Regulation Worst case deviation at the DC output voltage at the Point of Regulation (POR) for all operating and environmental conditions is less than ±1%. No turn-on overshoot. Remote Sense The remote sense lines, when connected to the desired POR (typically at the load) will compensate for up to 2 VDC drop on the output cable. Step Load Response Less than ±1.5V or ±3% (the largest) over/under shoot with recovery time of less than 0.5mS for any 50% load step within the range of 25% to 100% of the full rated load. Ripple Less than 0.25% or 50mVAC (the higher) for all operating and environmental conditions, except that at light loads (below 10%) it may rise but will not exceed 1% or 200mVAC (the higher). Isolation Output is galvanically isolated (“floating”) from chassis (> 20 MΩ at 200 VDC). May be grounded at any polarity. Current Limit & Overload Protected from overload and short circuit for indefinite time. Output is current limited (clamped) to 113±12% of the rated current. If an overload pulls the output to below 50±10 % of the nominal output voltage for more than 200mS, the output will shut down for 2 seconds before attempting to recover. Efficiency 91% typical. For minimum efficiency see Page 7. Overvoltage Protection Automatic shutdown (latched) if a fault results in above 115±5% of the nominal voltage. Resets upon the recycling of the Inhibit input, or by removing the input power. Will not trip by any AC input transient or step-load (including an abrupt load removal). Over Temp. Protection In case of an Overtemperature the M9204 will shut down and will recover only when its temperature drops back to normal.

The BIT_ RTN signal can be tied to VDC_RTN or any other signal or Ground. 2. When the INHIBIT input is shorted to VDC_RTN it disables the DC output. It can be a small-signal switch, or an electronic device such as the transistor of an optocoupler or an open-drain signal. 3. The signal’s level (Volts per Amp) can be adjusted by selecting the value of R1. For the mirror factor (K) and the maximum value of R1 that ensures full scale reading, see Page 7. Placing R1 near the sensing circuit (Op-Amp, V-Comparator or A-to-D) will ensure that the accuracy of the reading will not be affected by the voltage drop on the VDC_RTN feed lines. 4. To meet MIL-STD-461G radiation limits, the DC-output and Signal cables (J2 and J3) should be adequately shielded. 5. To enable current sharing when using a few identical M9204 in parallel: All +VDC pins and P_SENSE of all parallel supplies should be connected to a single point. All VDC_RTN pins and N_SENSE of all parallel supplies should be connected to a single point. The LOADSHARE pins of all the paralleled supplies should be tied together. 4.7KΩ +5/3.3 VDC +VDC BIT_RTN BIT (Optional, Note 1) M9204 Load (user’s system) K mA/Amp (Note 3) VDC_RTN INHIBIT CRNT_MNTR Inhibit Switch (Note 2) System’s Signals Ground Op-Amp (Note 3) P_SENSE +POR N_SENSE -POR
