Currently in development now avaliable for pre-order

Jump to: Switch Types Isolation Power Supply Cooling Additional Features

Switch Types
Selectable for each switch channel separately

Standard

Dual-level switch
  • Output Out switches between two voltage levels Vneg and Vpos
  • Vneg ≤ Vout ≤ Vpos must be fulfilled at all times (even when the switch is deactivated)

Option T (Trilevel)

Three-level switch
  • Output Out switches between three voltage levels Vneg, Vmid, and Vpos
  • Vneg ≤ Vout ≤ Vpos and Vneg ≤ Vmid ≤ Vpos must be fulfilled at all times (even when the switch is deactivated)
  • For applications such as injection, compression and ejection of ions

Isolation
Selectable for each switch channel separately

Standard

  • Maximum isolation voltage: 2.1 kV
  • Maximum burst frequency: > 10 MHz
  • Minimum pulse duration: < 50 ns
  • Propagation delay: 65 ns
  • Jitter: < 1 ns

Option H (HV Isolation)

High-voltage isolation
  • Maximum isolation voltage: 3 kV (5 kV or more upon request)
  • Maximum burst frequency: 2 MHz
  • Propagation delay: 120 ns

Power Supply
Modification of entire device

Standard

  • Nominal operating frequency of the auxiliary switching regulators: 125 kHz
  • Optional dithering control

Option N (Low Noise)

Power supply optimized for low noise level at the switch output
  • Shielded transformers
  • Nominal operating frequency of the auxiliary switching regulators: about 28 kHz
  • Low high-frequency noise due to resonant converters
  • Optional dithering control

Cooling
Selectable for each switch channel separately

Standard

Passive heat sink

Option F (Fan)

Active cooling via temperature-controlled fan

Option W (Water-Cooled)

Active cooling via liquid-cooled heat sink

Additional Features
Selectable for each switch channel separately

Option E (Enable)

TTL input for enabling or disabling the switch
  • Connector: BNC socket
  • Input level: TTL
  • Polarity selection: slide switch on the rear panel

Option M (Monitor)

Monitor output
Typical technical parameters (other variants available upon request):
  • Output: 1 BNC socket per switch channel
  • Nominal load: 1.0 MOhm + 1030 pF
  • Damping: 1:100 at nominal load, 1:50 without load

Option O (Offset)

External offset voltage
Typical technical parameters:
  • Voltage input: 1 SHV socket per switch channel (upon request: LEMO or Amphenol)
  • Maximum offset voltage with respect to ground: ± 500 V (upon request: ±1 kV or more)
  • Cut-off frequency of the filters: according to customer's requirements, 1 kHz typ.
  • Internal resistance of the voltage input: 100 kOhm typ.
