User manual EXACTPOWER EP15A

[. . . ] In this case you should under no circumstances try to power the unit on, as there are hazardous voltages present in this unit that can cause serious injury if they come in contact with you. 1 Locating the Exactpower Unit The Exactpower unit should be located on a stable surface with proper ventilation. Although the Exactpower unit produces little heat during in operation, the heat it does produce needs to be vented away . Please leave approximately 3" to 5" above the unit and do not block the slots on the bottom or the top of the unit. [. . . ] This process of powering your system removes the "turn-on" stress on the power line to a minimum, see item 2 below. Use the Exactpower power switch to power on and off your system . This may be convenient, but may cause problems . If your system has many different units the "in-rush" current to power them may be significant to open the fuse on the Exactpower or trip the circuit breaker on the power service box in your home. Front Panel Display On the front panel is a Vacuum Florescent Display (VFD) . This display has multiple functions and provides diagnostics for your Exactpower unit . Each function is described as follows: · · Power On: Upon initial power on, the display reads "Exactpower, EP15A". Output Voltage : The output voltage will be displayed after the power on page times out. The voltage is measured in true ms (Vrms). Output Current: Push the black button directly below the display and the output current will be displayed . Push the black button again and the display shows output power in Watts rms (Wrms). If you wish to not have the display show any of the above values, push the button again and the display will show a small indicator in the upper left hand corner of the display to indicate that it is on. · · · Protections The Exactpower has several protection mechanisms that will protect your equipment as well as your Exactpower unit. · Over Voltage : In the event that the voltage at the input of the Exactpower unit becomes greater than 245VAC the over-voltage protection "turns-off' the output to protect your equipment . The unit will attempt to turn-on again and if the over voltage fault is still present, the unit will turn-off again. 3 · Over Temperature: In the event that the internal heatsink temperature reaches 90°C, the Exactpower unit automatically switches into bypass mode and directly connects the input AC to the output receptades . When the heatsink temperature has cooled, the regulated output will be connected back automatically. Over Current: If the output peak current ever increases beyond 25 Amps p-p, the output of the Exactpower will be switched to the input or will be unregulated. The Exactpower will switch back to the regulated output automatically. If you continuously hear a clicking sound (about 4 sec intervals) in the Exactpower unit, the over-current protection is being triggered continuously. This is due to exceeding the output power capabilities of the Exactpower unit. [. . . ] Turn on the EP15A by depressing the power button. Select the wattage mode of the EP15A by depressing the mode button until "WRMS" appears in the display window. Begin turning on your equipment plugged into the EP15A one at a time observing the wattage displayed in the display window. [. . . ]
