MVCS Systems
MVCS-Series – Iontophoresis Amplifiers
Features:
Last Updated on January 27, 2022
In principle, MVCS systems are available as:
Fast systems (MVCS-C-02C) are delivered with headstages, ground connector, a power cord and a user manual.
Slower systems (MVCS-02C) are delivered with connectors for electrode connection and ground, a power cord and a user manual (without headstages).
Standard voltage ranges are ±45 V or ±150 V. Other ranges are available on request.
NOTE: All MVCS systems are also available as one-channel versions and one-channel versions can be ugraded to two channels. Furthermore, all version can also be ordered without a balance channel.
Please contact npi electronic or your distributor for details.
Use window to the right to look for popular options and additional accessories (at additional costs). Customized configurations are possible, please contact npi electronic.

MODE of operation:
set with two toggle switches, EJECT / RETAIN / AUTO switch enables manual or TTL
controlled operation
SET / OPERATE switch connects automatically electrode outputs to an internally grounded load, to make possible well defined presetting (SET position)
COMPENSATE / OFF / EXTERN switch (balance unit), selects compensation signal or connects
balance module to external signal source (additional channel).
HEADSTAGES:
Size (approx.): Standard 70x30x25 mm, holding bar diameter 8 mm, length 150 mm (±15 V, ±45 V), optional: 100x50x20 mm (± 150V) or 225x40x60mm (± 225V).
Electrode connector: BNC connector, (headstage with driven shield also available).
Ground connector: 2.4 mm connector.
Electrode output: floating current source, output impedance >1012 Ω
ELECTRODE RESISTANCE TEST:
1 mV / MΩ at the voltage monitor Vel / 10, obtained by application of square current pulses,
±10 nA from built-in pulse generator.
EJECT:
ten-turn control, switch selected range max. 1 µA / 100 nA.
RETAIN:
ten-turn control, max. 100 nA.
CAPACITY COMPENSATION:
range 0 30 pF, ten-turn control.
MAXIMUM CURRENT:
150 nA (±15 V), 450 nA (±45 V standard voltage), 1.5 µA (±150 V) into 100 MΩ load. Other ranges available on request.
OUTPUT CURRENT POLARITY:
selected by INVERTED / NORMAL toggle switch.
BALANCE OUTPUT (MVCS-X-02C-45, MVCC):
inverted sum of all currents, sensitivity 1 µA / V, for connecting external balance module.
TTL INPUT (AUTO mode):
LO = RETAIN, HI = EJECT, isolated, Rin > 5 kΩ
ANALOG INPUT:
sensitivity 100 nA / V, Rin > 100 kΩ, range ±10 V.
CURRENT MONITOR:
sensitivity 100 nA / V, Rout = 250 Ω, not isolated.
VOLTAGE MONITOR:
Vel / 10, Rout = 250 Ω, not isolated.
DISPLAY:
current XXXX nA, balance current XX.XX µA, voltage XXX.X V, REL XXXX MΩ,
separate displays for each channel, displayed value is set by a three position toggle switch.
OVER LEDs:
activated 10 % below maximum current.
POWER REQUIREMENTS:
115 / 230 V AC, 45 – 60 W.
DIMENSIONS:
19″ cabinet, 19“ (483 mm), x 10″ (250 mm) x 3.5″ (88 mm).
