Mastervolt Guarantee Plan • 5-year product warranty • worldwide service • 48-hour replacement service
SAFETY DEVICES
General galvanic separation between DC and AC side, by means of a class II HF transformer
Island protection • ENS models: redundant impedance, voltage and frequency window monitoring;
independent switch off by two pole relay and solid state switch; VDE V 0126-1-1:2006 compliant.
• QNS models: redundant voltage and frequency window monitoring;
independent switch off by two pole relay and solid state switch.
Temperature protection power derating at Ta
mbient
>40 °C; switch off at Ti
ndoor
>90 °C
DC side protection • earth fault detection • over-voltage detection
• polarity protection (diodes) • current limitation
• transients (varistor and buffer capacitor) • overload (temperature controlled power derating)
AC side protection • current limitation • over and undervoltage
• over and underfrequency • short circuit (ceramic fuse)
• transients / surge (varistors)
Reclosure time 10 to 300 s (model dependent)
MONITORING
On the front six LEDs for indication of power and system diagnosis
External communication two RS485 connections to connect to the QS databus
Monitoring (optional) • QS display: integrated LCD (standard for ENS models)
• Data Control Basic: software for PC (shareware from www.mastervolt.com)
• QS PC-Link: to connect the QS databus to the PC
• Data Control Premium II: datalogger and software with telephone and modem dial-up facilities
• Data Control Professional: datalogger using meteo data from the internet
