AC Power
AC supply is connected via the standard configuration IEC chassis plug on the rear panel,
100 - 250 Vac, 50-60 Hz (40 VA Minitrend QX, eZtrend QXe and 60VA Multitrend
SX). Absolute limits 90V-132Vac (110V) and 180V-264Vac (240V)
24V AC/DC Power / 48V AC Power
For the Minitrend QX and the Multitrend SX the supply range is 24V DC +/- 10% (ab-
solute limits are 20V to 55V DC). Also accepts 20 to 30V AC. Power to the D.C.variant is
connected via a rectangular 3-way connector as identified in Figure 2.3 on page 14 for the
Minitrend QX and Figure 2.4 on page 15 for the Multitrend SX.
The eZtrend QXethe supply range is 24V DC +/- 10% (absolute limits are 20V to 30V DC).
Also accepts 20 to 25V AC.
CAUTION
UNIT DAMAGE CONTROL
To protect against component failures the user should fit an external fuse for the DC
input power supply. The value should be 4A, time delay, high breaking capacity, mini-
mum 60Vdc.rated.
Failure to comply with these instructions may result in product damage
WARNING
HAZARDOUS VOLTAGES
When using the recorder as portable equipment the optional rear cover must be fitted
when hazardous voltages are connected.
Failure to comply with these instructions could result in death or serious injury.
