Accepting a wide range 90 to 264Vac, 47-440Hz input, the QS7 can deliver 1200W, the QS5 600W and the Q5H up to 1200W at high line and 700W with a low line (<180Vac) input. Three standard output voltages are available; 12V, 24V and 48V. The standby/signal option can be configured with output inhibit or enable remote on//off, a PMBus™ interface and a 5V 0.25A and/or a 5V 2A standby voltage.
Case dimensions for the QS5 and QS5H are 127 x 63.3 x 270mm (W x H x D) and 176 x 63.3 x 270mm for the QS7. The QS5 and QS5H are available with an IEC 320 input connector, replacing the screw terminal block. Operating ambient temperatures are -20 to +70°C, with output power and output current linearly derating above 50°C to 50% at 70°C. The use of low speed fan cooling reduces audible noise and also significantly reduces the ingress of dirt and other contaminants, improving product reliability. All models in the QS series have a seven-year warranty as standard.
The power supplies have 4,000Vac (2 x MoPPs) input to output, 1,500Vac (1 x MoPP) input to ground and 1,500Vac (1 x MoPP) output to ground isolation. All models are certified to the IEC/EN/UL/CSA 60601-1, ANSI/AAMI ES 60601-1 and IEC/EN/UL/CSA 60950-1 safety standards, (designed to meet IEC/EN 61010-1), with CE marking for the Low Voltage, EMC and RoHS2 Directives. Earth leakage current is less than 300µA, and complies with the EN61000-6-3:2007 and EN60601-1-2:2015 (curve B conducted and radiated) emission standards. The units also meet the EN60601-1-2 and EN61000-6-2 immunity standards and are designed and manufactured under the control of ISO9001 and ISO13485 (including risk management).
